Multi-purpose guide/richfield question?

I have a Tec 140 mounted on a GM-8. I do binoview and have utilized a Rigel quickfinder. I was considering adding a finder/richfield scope to take the Tec deeper, more easily and perhaps with the right set-up could use the finder as a quick peek scope. I was thinking along the lines of the mini-borg 50mm or a pentax 65-edf or maybe even a televue ranger. As a bonus, I could flop a camera into the guy but I am visual. Thanks for your help guys.

A fellow member of the Denver Astronomical Society mounted one of Tele Vue's small scopes (TV-76, I think) on his 5-inch refractor. It works nicely as a finder, and provides some superb low power, wide field views.
