I had the SeaDoo Explorer DPV for a couple of years. It is has the best propulsion of any of the SeaDoo scooters. It has three speed options. I found the fastest speed to be barely adequate while streamlined on breathhold. The draq created by SCUBA gear would really cut down on the performance. It cost around $750 at a Diver's Direct in Florida two years ago. I think it was rated to 50 meters. The battery would last me about 70 minutes and took around 12 hours to recharge. There is an issue with the batteries though. After the battery is fully charged (green light) remove it from the charger (vertical position) and lay it down horizontally while being stored. I wouldn't recommend going with any other SeaDoo DPV's as they are all underpowered in my opinion.

I have also used Silent Submersion's UV-18 and I highly recommend it even though they are a bit pricey. (http://www.silent-submersion.com/uv/uvprices/Prices.htm)

Hope this helped.
