I did a HEQ5 conversion and it was great, but one of the motors was unreliable So it's been sat on the shelf ever since. All in good condition but each motor has a small hole drilled (was for a stabilisation pin).
I'll sell the kit for half what it cost me to get it from the states - 75 bucks + postage.
But I'll repeat - only one motor is reliable (actually, the motor is fine, it's the cheap plastic cogs that are at fault).
Like Astrojunk, I converted my trusty TV systems mount using the DS motor kit, and like him I found one of the motors was pretty crappy. Ended up buying another set from Bill Vorce. I'll check at the weekend what bits were "left over"
If you're interested PM me.
