As far as plastic models go, this is an EXCELLENT hobby store. In fact, this is the best HobbyTown USA I have visited so far (California and Nevada).
Their plastic model collection is quite complete with large collections of military vehicles, aircraft and car models. They also have the most complete collection of aftermarket resin parts for any HobbyTown USA store I have been to. In fact, they have more models than some dedicated plastic model shops I have been to.
If you are looking for reference books, they have them too. The books are not wrapped up and you are free to read them before purchasing them.
Also, their staff is very friendly and I was greeted when I entered the store. This is something you don't get a lot of nowadays as far as hobby stores go.
Bottom Line: If you are in Las Vegas, make sure you make a trip to this HobbyTown USA branch. Also across the street is another store, Hobby People, so you get a two-for-one deal in one taxi trip!
