Duke, As Fisherman1 said do your homework and get something fit your needs. I just recently purchased a Intex Mariner 3 inflatable boat. Its perfect for me because I can roll it up and store it almost anywhere as well fit it in my mustang. I use mine primarily for small ponds but then I have added a few things to make it comfortable on a lake for a few hours.

As for accessories, a lot of inflatables can just about have anything a kayak can. On my inflatable I have mounted a trolling motor, fish finder, wood floors. Of course the more you have with it the less mobile/convenient it becomes.

Here is a picture of mine below.



This picture was after we were done so its a mess. But between the seats I can put a full size cooler!
