I used to be in your situation when I had my condo. I bought a Sea Eagle SE9 inflatable motor mount boat. I still use it, just had it out this weekend. It takes about 15-20 minutes for me to set it up with an electric pump, but the plus side is it stores in a large Rubbermaid tote when not in use. I also have the floorboard which makes standing easier. I can motor around for hours with a trolling motor, or paddle it. It also has a very shallow draft allowing me to take it anywhere I can take a canoe or kayak.
As for durability, I've bumped mine off of rocks and trees without any issue. They are pretty tough boats. I'm actually on my second hull, the first one had an issue with the floor, and Sea Eagle sent me a new one. Their customer service has been top notch in my experience. The reason I mention that is the old hull still held air in the 3 main chambers, so it became an oversize pool toy. During a party 8 of us had it in the pool and tried to see how tough the boats really were. Between us filling it with water, overloading it with people, flipping it over, and other horsing around we still didn't hurt it. That hull lasted for a few years of pool duty basically being subjected to the same abuse. The only reason we got rid of it was because we were cleaning out the basement and didn't need the second hull anymore.
