Center Console Boats And More

Need help choosing inflatable fishing boat with room for 4?

hi so far i am looking at the sevylor fish hunter 360 (12ft model) , the intex seahawk II , and the intex excursion 5. i dont have a lot of money nor the room to store a REAL boat so ive narrowed my search down to these three (unless somebody has a better suggestion that is). i will be fishing a local lake maybe once a month. it'll have to support up to 4 adults at times ( 5'8-6ft 170-200lb-ish dudes) i plan to add a ply wood floor with a layer of foam and outdoor carpet, and a 30-36 thrust minn kota trolling motor. any opinions on which boat / raft to go with will be greatly appreciated. i am already thinking i might need to haul a small el cheapo walmart raft on the side to hold the ice chest and some grear.
basically put, i need the most room possible but yet stable.

which intex?
thanks guys.. after some further research i am now looking for a used ( 10' +) zodiac or achilles dingy.
