When I first moved my photography business to Vegas there where only two real camera stores in Sahara Camera and Casey's. Camera Tech used to be pretty good, but Ike let the place burn down and ruined it for everyone! After Fred died, (RIP friend) Sahara Camera quickly deteriorated and closed. Leaving only Wayne's store, Casey's now.
Being last, it wins by default and I've frequented Casey's for 11 years it was the first place I ever bought gear in Vegas. It may be the last professional photography equipment store in Vegas.
I know I've spent WAY to much money there, mostly because if I need it, Wayne either has it or knows who to call to get it.
I highly recommend this store to everyone in need of photography gear in Las Vegas.
Check your attitude at the door because they do not suffer fools, but they are helpful if you ask.
