Hand Controlled Dual Axis for a Dob?

Is there a stripped-down hand controlled dual axis drive with clutches for a dob? Seems it should be reasonably easy, less compex, and less expensive than tracking since it would be essentially an on-off system. Perhaps someone has done this from scratch?

You guys better not let John Dobson hear you talking like this!

I've tried Mel Bartel's system, but it required a lot of tweaking and you also needed a laptop. I retrofitted a Meade DS mount onto my 14" truss. All the brains are in the Autostar controller. Total cost for parts was about $200. Here's a link to it:

I bought some new 1.25" tubes a few weeks ago so that I can redo my 14" into a more lightweight scope. I'm also going to redo the GOTO setup. The altitude speed is fine, but the azymuth speed is excruciatingly slow. However, the GOTO's are extremely accurate!

I used DS motors, but motors from an LXD55 or LXD75 mount could also be used.
