I'm sorry that you think of Sarasota as a wasteland. I've been here since '81. Now I don't have the experience of LA or Denver to compare to, but I make due. I order on line, get stuff in a few days. No point in complaining. We got those white sand beaches and balmy days!
There is a used photo show up in St Pete at least once a year that seems to have all kinds of stuff for you to salivate over. I think Nancy Green runs it.
You might want to try North Tampa Photo, or Colonial Photo in Orlando.
