I'll chime in with my own personal experience having been on both sides of the dilemma before. I started in a Wilderness Systems Ride 135, spent time in the Tarpon 120 and 140, the Ocean Kayak Trident 13, Native Watercraft Ultimate and ultimately made my way through the Hobie lineup of the Outback, Revolution 13, Pro Angler 12 and now the Pro Angler 14. I also have had hands on and interactions with manufacturer and pro staffs for all of the major brands as well.
Having said that, the ultimate choice of kayak is a product of a number of factors:
1. Your fishing style 70-80% of the time
2. Your target species
3. Your preferred waters 70-80% of the time
4. Your physical limitations
5. Your storage options for when the kayak is not in use
6. Your method of transporting (that includes roof top racks systems, truck beds and trailer options)
7. Your budget (needs to account for all costs including paddle, pfd, racks, etc)
For me, I always wanted a Hobie, but like you mentioned, the initial cost factor was a hinderance for me at the time. After spending countless amounts of money on rigging and kayak hulls, I ultimately found my way into a Hobie, albeit the heaviest solo seat model prior to this summer's release of the PA17T.
If weight is a concern, let me add a different perspective - I loaded my 2013 PA14 and my current 2014 PA14 on top of my Dodge Grand Caravan by myself by using physics to my advantage. I now load my PA14 on top of my Honda CRV solo using the same method and have no problems whatsoever, so in my opinion weight is not a reason to avoid a Hobie. Most traditional 13-14' kayak hulls weigh 70-80 pounds, so the 20-30 pound difference is negligible in my opinion when you consider proper loading and unloading techniques.
While cost is also a valid concern, you have to look at the total cost of any kayak you are considering purchasing. I can tell you with a fair degree of certainty that you will add another kayak at some point, whether due to limitations of your first hull purchased, wanting a spare for family and friends or realizing you made a mistake in your initial hull choice. We all end up adding at least one more at some point. I myself sold two of mine to get into the one I have now, and I will be adding at least one more in the very near future. Most likely a Revolution 13, Outback or a Quest 13 (paddle version of the Revo 13).
I can tell you that my original Ride 135 cost me around $1000. What tha cost did not include was the items I added that being a good starter paddle plus I added a high end carbon fiber paddle ($450) later on, a seat upgrade (twice at $250 toal cost), a nice PFD ($100), a rudder kit ($200), a fishfinder and battery setup twice ($250 first, then $600 later), several rod holders, anchor trolley, crate system, cart ($200), rack system ($400), etc.....as you can see the costs add up. There are ways to save money either through DIY modifications using household or big bix hardware store pieces or even through the secondhand market (eBay, CL, wanted ads, word of mouth, etc). My only caution there is ensure you can test out the items before committing to a purchase. In the end, I spent well over $2800 in total after taxes within the first two years of owning my first kayak.
By comparison, my first Hobie Pro Angler cost me $2500 in total and it included the factory 8 rod holders (6 horizontal and 2 vertical), the Hobie paddle, a comfortable seat, integrated Lowrance depth finder setup, a Hobie cart and anchor trolley. I added a $300 depth finder and $100 Hobie battery kit for a FF. In other words, I only spent $400 more and I didn't have to customize or perform any DIY modifications to the hull.
In short, the total difference between the two purchases - $100 more for the Hobie in the end. My Revolution 13 I had prior to the Pro Angler 14 was even less. It came with 2 vertical rod holders, a paddle, a high back seat with adjustable lumbar support, an integrated rudder system and cost me only $1500. I added the $600 FF setup to it bringing my grand total to $2000 for that setup - far less than my earlier Ride 135.
Don't fixate on the initial sticker price - you have to price out the entire package. That's not to say that your budget will allow for a Hobie, it's just pointing out the realities of purchasing a kayak. Also, don't force yourself into believing that you have to focus on just the Pro Angler series, there are other options in their models both Mirage Drive versions and paddle based. Keep an open mind!
If you have any more questions about any of the Hobie lineup, just ask away so others can see it and benefit from your questions and the answers.
