I use a Pelican 100 angler. It is a sit inside and costs around $400. I personally wouldn't trade it. I've fished with others in different kayaks and the advantages to this far outweigh the disadvantages. I can go in a lot rougher water than most sit on top I've fished with. I can go in cold water and not get wet. It fits in the trunk of my ford focus with the seat down. I don't have to worry about gear falling out (it is inside with me). It's warmer in the winter and cooler in the summer (sitting inside water cools the inside and keeps wind out in winter). I can go from kids in bed to on the water fishing in 20 minutes. Don't have to worry about launching as I can launch from any shore bank and carry or drag it anywhere. Trolling is easy with a bit of practice. The value of the kayak is pretty much the same used as new. It takes up next to no space hanging from the roof in my shed.
I don't really have any negatives to it. I have fished with others in sit on top and found that my little $400 kayak keeps up with the sit on tops. I mainly use mine for the grand river. I Can't add a trolling motor and it'd be difficult to add go pros.
