As someone who was an avid kayaker before integrating fishing into it, a couple of notes:
1. Peddle kayaks are awesome but you're not going to find one under $1,000. Even used will be difficult.
2. I bought my first kayak, an Eagle Talon sit-on-top for I think $450 during a Black Friday sale. We're right around the corner from it and I'd highly recommend waiting.
3. If you buy a kayak that doesn't have all the bells and whistles you want you can add a lot of that stuff later. Really just need capacity and determine whether or not you want to stand on it as those are the two things you can't really change (you can stand on anything with outriggers, though getting up you might have to add your own strap or something). I supposed peddles would be in there too.
4. If you choose to add stuff to it, 90% of the time you can make your own version of whatever someone is charging an arm and a leg for. My kayak originally had a sit in seat and I have since added my own version of an elevated seat I made with PVC pipe and a stadium seat thingie from Dicks.
5. If you're not opposed to used, you'll find way better value via Craigslist, FB Marketplace, etc. Main things to look for used are where it was stored. If it's older, stay away from anything that was sitting outside. You can generally tell how much and often it was used by the scrapes on the bottom.
6. Figure out where you're primarily going to be using it. Personally, my next yak is going to be a Jackson Coosa HD. I'm not getting the FD (pedal version) because it's exponentially more expensive, but I primarily do in-shore fishing in a lot of very shallow rivers and the Coosa is a little wider so it doesn't sit as low in the water and can handle it better.
7. You can buy little wheels to transport your kayak to and from the water that make it easier if you wind up getting a heavier one. Would recommend it as one of your first upgrades.
Again, to reiterate, you don't have to deck out your kayak with everything right away, and when you do there are a metric ton of videos on YouTube on how to do a lot of it yourself, like a milk carton storage rack and rod holder that takes care of the vast majority of add-ons.
Good luck!
