So you swap back and forth from the telrad to the guidescope i take it?
Now that I do plate solving, the telrad only goes on for visual.
I don't have experience with the cheap finder scopes modded to be guide scopes, so I can't help there. I would worry about the plastic-looking thumbscrews on the one you linked. I am not a fan of the rings with the clamps like this, as they leave room for vibrations. However, lots of people use them, so I can't help on if it is appropriate.
The one I use is a MiniBorg with tube clamps, and an ADM mini-max for aiming. But I rarely need to bother with the mini-max, as the LodestarX2 is sensitive enough with a 50mm guidescope that its rare I don't find a star to guide on.
