I would highly recommend going the used route. I made the mistake of buying my first yak new before realizing I could've had a much better 1-2 year old boat. My first yak was an Ascend 12T which I was fortunate to buy right before their substantial price increase (went from $650 to $800 a month after I bought if I remember correctly) and sell after that increase, so I didn't lose but a few hundred bucks. My second yak was a very well rigged NuCanoe pursuit I picked up for $900 and sold 4 years later for $1700 (with a busted Xi3 Spotlock I had added). I've moved on to a jon boat now, but would never buy a kayak new again.
Not sure how much kayak fishing experience you have or what your goals are (fun fishing vs tournament), but once you experience fishing from a kayak with a motor or pedals, you'll never want to go back. You can't fish effectively with paddle in your hand, so you're giving up a lot of actual fishing time by paddling. If you're tournament fishing, you don't really stand a chance in a paddle kayak against guys in pedal or motorized kayaks.
I'd think if you spent enough time on marketplace or similar, you could find an older pedal drive yak for around that price point. And if you decide to upgrade again in a few months, you'll be able to sell it for close to what you paid.
