We had a '96 Sea-Doo, and loved it! It was a very dependable craft. But I've heard the newer ones have problems with their engines, but don't know specifics. Kawasakis are supposed to be pretty good.
Yes, these things are a blast!!! But unfortunately I had to sell mine a month ago. Getting rid of toys before we move this summer.
