I'll be in Vegas soon and plan to do some good hobbying.  My hotel room will have a vhs player (with the possibility of dvd) and i'm thinking it would be fun to have some video accompaniment to the live action--some movies playing to set the mood.  Does anyone know where i can pick up some cheap used videos?  since it's only for a few nights it's not worth getting new tapes--but if there's some bookstore/adult store that has a decent selection of old tapes/dvds, that would be excellent.  I know vegas a little but it would help if you can give a basic address or info.  
thanks!  (and sorry if this is off-topic)
