I'm new here but have some experience in a short time with kayaks. I agree with bholtzinger14. Check the Vibes out. I have a Hobie Outback, Jackson Cuda 12 and two Stealth Anglers made by Lifetime from Cabela's. I would put the Vibe Sea Ghost up against my Cuda as far as what you get for your money. My buddy just bought one and I'm jealous compared to my Cuda.
Also, maybe it's just me but a sit-in are just asking for trouble. If you get into water that's over your head it just scares me. When they flip they're going down. You can turn over most SOT kayaks and they will still float as long as the hatches seal and if they do leak it's gonna take time. The other is going to the bottom.
