Beginner Recreational Kayak

I've been really interested in getting a recreational kayak and getting out on White Rock Lake (I'm in DFW) and other local lakes/streams.

I'm not interested in fishing out of a kayak, so purely just recreational. I've been reading and most suggest a sit on top kayak. I gotta say I was hoping for a sit in b/c they seem to offer more storage space and the ability to go out and not end up with a wet butt.
They say the sit on tops are easier for beginners though. I was thinking I could compromise with a sit in that has a big opening cockpit.

Anyway, I want to keep it under $500 and the lower the better. I don't know how often I'll go out or if this is just one of those things I'll spend money on and forget about in a few months. So I'm not looking to spend a ton. If it's something I love, I can always upgrade.

So I've got Academy, Dick's, REI, Cabela's, Bass Pro Shops, Gander Mtn(if they're still open) all by me. Any particular brand? I see Pelicans for cheap that look ok for my purpose. Also like Perception kayaks under $500.
