Are there any places to get decent roller derby skates in Salt Lake City?

I have been searching high and low. The only quad skates I have been able to find are the "roller derby" brand name, which I have read are actually the worst ones you can get for roller derby. How is a girl supposed to try on skates, if nobody sells skates in a store? My funds are somewhat limited and I need some of the entry level skates rather than the really nice ones I actually WANT.
