Re: [PSUBS-MAILIST] Opinions About Design

George,

I'm sure you're familiar with the VideoRay then....http://www.videoray.com/

Their solution for vertical maneuvering is truly very clever..a small reversible motor hidden in the float. Check out their mpegs, the thing dances on the end of that tether with precision.

Someday, with the time on my hands to do so, I would really like to duplicate something like this, right now, I think they want 6k.

Incidentally, I did contact them some time ago, all individual components are available, there is a pricelist on the site somewhere.

Joe
