Brett,
For your 10" dob, I would recommend a Telrad, if you can cope with the $/size/weight issues. Otherwise a Rigel QuikFinder.
I have a Telrad on a 8" solid tube dob. It is really nice to use, isn't fussy about eye position and the 3 ring/4 degree reticle is excellent for a light polluted environment.
The Rigel QuikFinder is much lighter and smaller then the Telrad. I find it is more critical for eye position and the reticle is only 2 ring/2 degree which is not as helpful in the more barren areas of the sky. I have one of these on my 8" stringscope dob and I am happy with it.
Until recently I had a red dot finder (Andrews 25mm) on a 70mm F5 refractor. It was quite satisfactory for general pointing. The dim seting was too bright for DSO work at a dark site but fine for casual suburban use. I had to modify the mount as it was too flexible. For commonality reasons I have now replaced this with another Rigel QuikFinder.
Cheers,
