If you looking for advice, don't buy that one you linked, a "sit-on-top" style. It's a beach toy not a fishing rig, and it's overpriced to boot. I don't meant to be blunt, but I've watched people buy those, use them one time, and they never get used again.
Sure sit-on-tops look like easy access, but once you go out one cool morning you'll realize it's not all that fun to paddle around with a wet arse. My idea of fishing doesn't include letting my bottom soak in skimmed over stagnated pond water, and if your in good fishing water, it's not going to always be like good clean pool water, you'll be in mud, smelly old tree branches, moss, slime, bushes, scum, and bugs. The more enclosed you are the less of that stuff gets on you and stays in the lake.
A lot of times, people say: "But I'll only use it in warm weather, I don't mind getting wet." Well then you came to play at the beach, not go fishing. Even if your only a moderate kayak fisher like me, you may be out there for 2-3 hours, paddle a mile or two, and head out in cool morning fog covered water to paddle back in whitecaps with the sun and wind beating down. Might sound rough, but that's what I'm trying to tell you, an enclosed kayak makes it comfortable, a sit on top makes it miserable.
So, if I haven't been direct enough, get a sit in style, that means world outside, you inside. The Eskimo's knew what they were doing. If you go so far as to get a cockpit skirt and put on a raincoat and you can fish in the rain and still be moderately comfortable, not that you'd want to, but I speak from experience, weather can and does sneak up on you, even if you try to watch it. A summer pop-up storm can catch up with you even if your only a mile from camp and think, I'm just going out for a bit. Once I paddled back in storm force winds making big waves, but I felt very secure in my kayak and made it back to camp safely.
This is my fishing kayak, these can be had for about the $600-$800 range new. It has 3 rod holders, a dash board for a tackle box and is even rigged to mount a fish finder, even thought I don't use one. Paddle holders are very handy, and it came with an anchor and a cleat to tie it to. It's been very comfortable to fish from in varying conditions.
Good luck, kayak fishing is the only way to go in my opinion, who needs a boat to maintain, buy licenses for, and tow around. The big advantage to fishing from a kayak is you can go where larger boats only dream of going, back in creek channels and moss beds no smart boat owner will get near.
