I'd like to have one for my Duo Vue but they are already up to $31!
Wish they had sold them individually.

Pick up the pair, a spare is always nice!

but you need 3 to make color (unless you use a wheel)

Hmm. That's an idea. I've wanted to build a color wheel projector with
a Protelgram for a long time. The wheel would need to be only 15 inches in diameter, but the picture would be 25 inches diagonal.
Sounds like a good winter project. #;^)

I'd apologize for putting the idea in your head, but I know you'd enjoy trying it and I'd enjoy seeing it. :D

$46 and I forgot to bid on them.:drool:

Anyone here get them, want to sell one?
