Texas Towers is a nice store, but unfortuantely it's only open M-F, 9-5. For those of us who work during those hours, you can either mail-order from TX Towers (I've done so) or check Fry's. Granted, Fry's amateur radio stock is practically non-existant (although they do carry some excellent Larsen antennas), they do carry quite the selection of power supplies and test equipment. My favorite geek store is Tanner Electronics in Carrollton.
