Jason,
Absolute Vinyl in Boulder is a great store, 5360 Arapahoe Ave, Boulder, CO 80304. Doug and Anne Gaddy own the store and Doug has been doing this for more than 25 years. He accurately grades his records and cleans everything before it goes in the bins. Doug has exhibited and sold records at every RMAF, which is where I met them. Smaller selection than Twist & Shout, but good quality.
Twist and shout is good. I always stop there when in Denver visiting family. Also, Wax Trax Records,
http://www.waxtraxrecords.com/. It is in the same general area as Twist & Shout.
Black and Read Books in Arvada is worth the stop. Good indie selcetion the last time I was there.

Have fun
