I'm using a Telrad, previously a had red dot on a Celestron.
The red dot is quick and easy, two eye use, pretty good, perfect for getting stuff into the eyepiece at 60x (25mm Celestron Plossl) when properly aligned. (I prefer the word 'harmonised' rather than 'aligned'...has to do with fighter aircraft gunnery systems, but means right on target....)
I've gone to the Telrad on my new scope because I want to learn the sky. Using a good sky map, occasional use of binos to get into an area (particularly in light polluted suburbia), then using the Telrad calibrated circles to move about, I can get onto targets pretty easily. I can aim accurately enough to get an object in the lens (Pentax XW7) at 170x if I'm a bit lazy with lens changes.
Its not the best two eye finder. I fitted a dew shield (has a mirror installed to allow 90° viewing, and found that this made two eye use more difficult, but dewing has been stopped.
I am quite happy with the Telrad and can't see the need for anything else with my current set up.
