I too am in Denver and go to a place called 'Prince Phillips' which is on Hampden and Tamarac. Im not sure where you are. There is also a good palce on Iliff and Chambers.
Price Phillips has a great selction and prices are good, the only problem is the guy who reuns it isn't very freindly. The other place, Smoker Heaven, Doesn't have as good of a selection and are alittle on the pricy side but the people are very nice.
