Slightly OT: Favorite Computer Store?

Is there a computer shop here in Phx that caters
to the "hobbyist/enthusiast" crowd? This dealer
might have the following attributes:

*    Speaks knowledgeably about their product line

*    Minimal hassle about returns

*    10% discount for PLUG membership
        (Doesn't hurt to dream ... ;-)

*    Well stocked with the latest goodies

*    Weekend hours

I hope the answer is not "This is the age of
the mega corporation: go to Fry's, CompUSA, etc."
