I picked up the STAR WARS MOS EISLEY Adventure Set, on Ebay very cheaply last week. It's a boxed supplement for Star Wars The Roleplaying Game, published by West End Games in 1997.
The set includes a variety of resources including Galaxy Guide No.7: Mos Eisley, a Mos Eisley Adventure Set booklet (32 pages), a double sided colour map of Mos Eisley and the famous Cantina. The Cantina 'map' is more or less 15mm scale too. An unexpected bonus! Finally there's a quick set of scenarios, docking bay map and counters called Imperial Shootout.
If you see it at a good price I recommend you buy it. As the guide says, the Cantina can be any Cantina on any planet, Mos Eisley is just a pirate port that can be transposed to any world and Tatooine itself is a desert rock anywhere in the Galaxy.
