The Crown Point Show is a small venue with a mix of odds and ends.
Think of it more as a flee market sale with prices all over the place.
You *may* find a good deal (ie cheap price) but not always.
Some here will say that you can get better prices online & it's 90% true for most items. However the best thing about the CPS is that it's small, you can touch whatever you are looking at (can't online) and you can get one 1 on 1 time with the vendor.
@$5 with FREE parking it's a small amt to pay to go see and feel and do some research.

Also note that you can take your firearm (to sell if you like) to the show. Just UNLOAD it in your car (no AMMO allowed in the show) and have it ready (the firearm) to present to the LEO at the door. They will put a plastic zip tie on it.
Plus you might find some "odd & interesting" toys there. A few years back someone was selling one of these:
Knoxx Sidewinder. It's no longer made by Knoxx but was a converstion kit for the REM and/or MOSS so that you could use drums or mags to load up your SG.
