The nice thing about an actual Telrad, as opposed to the other red dot finders is that it is easy for the beginner to mount it (just sticks on the tube). Most of the others need an extra plate putting on or removing the finder. I find the magnified view in the finder is a big help for finding stuff that isn't visible to the naked eye, so I don't want to remove it.
EDIT: you will of course need some means of collimating first... but I'm afraid that goes without saying.

I recently decided on the Rigel Systems Quickfinder on my GSO 12" dobs.
The Quickfinder won the competition becasue of the following factors. It is
very light, has a very small footprint, is elevated by 4.5" off the OTA, fits between the focuser and 8X50 finder, and it has a built in blinking curcuit for finding really dull targets (this is an extra $$$ option for the Telrad). I have also noticed that the Quickfinder reticule windows is very resistant to getting dew all over it. Also the manufacturer will bend over backwards to help. And it is close to the same price as the Telrad.
