Kind of interesting information here considering how the Gavin scooters were developed...
For that matter SCUBA gear in general, this "sport" is only 50 years old and many of the pioneers both at the start and today were the ones building thier own systems.
Now if there is something out there cheaper or signifigantly safer or more efficient than my time I might make the purchase... But most of the folks here are talking about DIY for the joy of it, diving is all about ingenuity, its part of the thrill.
westcoastdiver:
Have you looked around some of the smaller ROV and AUV sites for ideas?
Kirby Morgan is testing a unit at the Dive Lab, it is designed for military applications though I believe. I remember reading somewere about this Naval proposal for insertion units... Kind of between a scooter and a SEAL delivery vehicle...
Keep us posted on your research, and keep tinkering!!

If you dont already know them, you need to know two people in your area:

but at the risk of spinning up any DIR Tech Diver(s) out there, here is a site with an interesting FAQ section:
http://www.silent-submersion.com/
While perhaps not as well known as the Gavin product, this product appears to provide equivalent performance. The description of production and design variations in the FAQ section is informative.
If you desire to build your own, it may provide food for thought.

Building a scooter for recreational diving is not that daunting a task if you have good tool skills, access to tools and a workshop, a PVC pipe supply, and a decent electric trolling motor. So far I've built 2, one very simple one based on 6" pvc pipe and parts from an old scooter that used to attatch to the bottom of your tank. The battery is too smal to have sufficient run time for my liking, but it works fine. The other is 8" pvc, larger battery capacity, and has the motor situated concentric with the main body tube. The motor fits nicely into a piece of 4" schedule 80 pvc. (use some strips of 1/4" vinyl tubing to make it snug, and allow water to circulate around it for cooling) and a hase clamp to hold it tight. Slide the 4" into a 6" to 4" reducer with the shoulder removed. (so the 4" slide all the way in thru) Cap the 4" on the inside. Cut a 6" dia short nipple (about 6" long) and connect the 4" to 6" reducer to a 6" to 8" reducer. Now add a piece of 8" pvc pipe as the body and use a 8" cap. You'll need to have a machine shop put O-Ring grooves on the body and make some O-rings. You'll need to get the battery out to charge it. Use a Gel cell. You'll need to do some math to see how long to make the main tube. You need enough flotation to maintain neutral bouyancy for the weight of everything, and to get the fore/aft balance point near the center. If you're savvy enough to actually build one, this should be enough info. All the details would take a lot more space. Hope this helps and good luck!

The best damb scooter ever made was the Farallon MK 5. faster than any scooter made today.
What about using a bilge pump? Make a simple two tube design: top tube has battery installed in it, and you could make a simple magnetic switch. Basically, make a paperclip switch, just use a magnetic metal instead of a paper clip and then strap a magnet on your hand 
You'd put handles on the bottom tube, since it doens't have to be watertight. In this second, bottom tube, you insert a bilgepump. Connect wires and boom you have a DPV.
Might not work at all, I really have no clue. I have a small bilge pump though, that's not in use right now
