Walther makes a great 22 hand gun(P22). It will run you between 300 to 350 new. Muzzleloaders if used make sure you ask for barrel light so you can look down the barrel and see if its be taken care of, in fact do that for every gun, even new ones too, just to be on the safe side. You can find 22 rifles fairly cheap. Just depends on how nice of a gun you want. Depending on the size of the show, id walk around and make note of everthing you like and then come back to it. Also, if its used you can discuss the price. Sometimes they will want to get rid of it so they will work with you, especially for the guns your looking at.
