I love fishing from my Kayak, at this point I have 2 Jackson kayaks, a Big Tuna and a cuda 12. Purpose build fishing kayaks are fantastic.
Around here the Hobbie pedal drives are very popular though more expensive. there are a couple more brands that have pedal drives.
In general it pays to go with the bigger brands Jackson , Hobbie, wilderness systems etc the accends you can get at BP will float you but that is about all
Even though pedal drives are all the rage (and I can see there usefulness), I can tell you paddles still work .
