Inflatable boats for fishing and messing around

Anyone have experience with these or know someone who has? I'm considering getting one mostly for fishing on lakes. I'd prefer one big enough to hold 4 or 5 people so I could take a few friends out with me just for fun. I'm looking for any help or advice concerning whether they're worth the time, money, effort, and if so, which one I should get. Even if you haven't had experience with them, I would like your input.

From the research I've done so far, which isn't much, it looks like the Intex Excursion 5 is the largest inflatable in my price range (<$500). They are only $150 just for the raft, cushions, and a couple throw-away oars.

Another option is the Intex Mariner 4 which is a little smaller but made to be more durable. The Excursion 5 is made of 30 gauge vinyl while the Mariner 4 has 3 layers, with the two outer layers being made of a tougher vinyl material (not exactly sure what makes it "tougher" besides the extra layers, but that's what I've read). Also, the Mariner 4 has a plastic hard floor that makes it more stable and easier to stand up in for fishing.

Each has multiple air chambers so safety is not my biggest concern. I would prefer avoiding having to do patchwork as much as possible, but I realize with an inflatable it's bound to happen if you use it.

The Mariner 4 runs at $270.

While I obviously prefer the Mariner 4 for its better overall quality, I really want that extra space, especially since I would put on an electric trolling motor with the battery taking up room in the boat.
