I agree with the above posters that it is personal preference, because everyone's needs and expectations are different. Some random questions off the top of my head anyone might ask and answer to themselves:
-Am I big guy as the limits are about 350# for a float tube, maybe go to a pontoon/raft beyond that?
-What kind of physical shape, to tell if you need motor power accessory with a toon/raft?
-How long will I be out, will it always be the same few places, how many times per year, and do if have the work schedule flexibility to select the weather when I go- tells comfort factors, quality/ruggedness needed?
-Do I have space to leave the tube set up and loaded or will I have to go thru inflation protocol and loading each time- tells amount on actual fishing time on the water?
-How will tube be transported and what is the most distance place I would go regularly- tells actual fishing time on the water?
-How much can I spend, how soon do I need it, and do I have a 100% satisfaction return policy where I buy?
If possible, go with someone that has experience and an extra tube to loan you to try out the concept. There are some details like adjusting pressure before/after in altitude or cold water, fin propulsion, traveling backwards, etc. which are best observed with someone experienced. If that is not possible, you can go alone and try a high rated tube shipped/returned from your nearby Wall Mart like:

Hope this helps.

I will be buying my first tube and don't know what to look for. I will be using it on a small, 25 acre lake that is close to my house. I will not have to walk far from my truck to launch. What are the pros and cons on different types? What accessories should I get or any?
Any help is appreciated
