As I have posted earlier in this thread, our St. Louis mini-chain (8 stores) not only carries Pentax, they PROMOTE Pentax.

Pentax Test Drive - Creve Coeur Camera
Service varies by store and salesperson. I frequent the used department (i consider my purchases and sales of old Pentax lenses akin to long-term rental). Sometimes I get annoyed if I want to buy something new - some salespeople try to steer me to Canon - but as I said before, the third time I say Pentax (if necessary) I also say "order online" in the same sentence, and I get what I want.
It does cheer the heart to see a B&M retailer promoting the brand.
