Agreed, Gamma Andromeda! Best double in the sky. Of course many say Alberio, which is of course beautiful. Some other real good ones are

Gamma Leo, both gold.
24 Coma Berenices, yellow and blue.
Epsilon Bootes, both gold.
Delta Serpens, yellow and blue.
Mu Draco, nice clean split at 2" of arc.
Omicron Ophiuchus, orange and blue.
95 Hercules, red/red, don't see many like that.
70 Ophiuchus, yellow/gold, real good colors.

The hardest one on the list was Gamma Virgo. Both stars are magnitude 3.5 with a seperation of 3". Now I've split stars down to 1" with my 12"LX200 and seen a clean black space between them. But with Gamma Virgo, the glare from two 3.5 magnitude stars is overwhelming. It's very difficult to see both stars. I got a real clear still night and was able to see both stars. I used real high magnification, not for the size but to cut down the brightness. Check out the list. It's lots fo fun and you don't need real clear skys. You can even do them under the full moon.
That's it;
