Telescope shops in AZ

I'm finding myself on a flight to Phoenix tomorrow on short notice.
I'm wondering if anyone can recommend a good place to look for the
following items typically in stock:

Coronado H-alpha filters with adaptor plates - ideal would be someone
that could demo one.
TV powermates 2"
Lumicon filters


I can get up to Flagstaff or down to Tucson pretty easily if
traveling is an issue.

Yeah, I know that I can order this stuff online, but I'm a hands on
type of person that needs to really see what I'm buying.
