All of the previous suggestions/comments are excellent, but you are failing to take into consideration the most important factor - what kind of water will you be fishing. Just like there isn't on fly rod/fly line that will serve all fishing situations, there isn't one style of boat that will fit all types of fishable waters.

You need to ask yourself how and where will you be using this boat 80% of the time. Will you be fishing out of this boat or will it be used as a means of transportation to places where you'll likely wade? What type of distances do you intent to travel when you are on the water?

If most of your fishing is in flat water (ponds and lakes) then you can use just about any type of craft, pontoon, canoe, kayak, jon etc. If you'll be spending most of your time in slow moving water then you may want to consider a SOT kayak. If you'll be in fast moving water a SI kayak or a canoe might be better.

How often will you be camping? Once or twice a year? If so, you can usually jurry rig something to hold your gear. But, if you'll be doing a fair amount of camping, you'll need something with storage space like a canoe.

Before deciding on anything, give a lot of thought to where you'll be using your boat.
