I have an Astrodon MOAG and a Monster MOAG that I used to use with my STL cameras. Given that I now have STXL cameras I no longer need these off-axis guiders. I haven't used them for a few years but I think they are still in good working order.
The Astrodon guiders are rather expensive new (around US$800 without shipping). I'm prepared to let these go for $380 each plus shipping or the nearest reasonable offer.
