Curt, the Reno Show (I've attended only once) has almost every type of gun you can imagine and prices are high to low.
Good place to go and see what is available, but don't expect most gun shows to look like this in any regard. Only larger ones have lots of guns, most have a few guns, and none to a hand ful of Lugers. Learning is great if you know someone and meet them, but not the best place to learn by your self or trying to get info from others who are busily looking for new guns
So, forums such as this is a great place to learn, buy as many books as you can afford (but searching this site is free **although I think every member should send John Dunkle $25.00 annually to help out with costs**
