RE: What boat should I get?
If you're asking me, I've only seen a modded Mini Rio run so far. One of my brothers got one for Christmas but I haven't been out to his house to see it run yet. The Mini Thunder just came out recently and I saw my first one at the Toledo show. Both are using the same everything pretty much, motor, ESC, radio system and the like ut I'd think that the Mini Thunder should be a hair faster.
Aquacraft does have a video on their site with the Mini Rio.
