Also, if you feel like coming to St. Louis, I have an extra Defender cabinet with sideart. (NOT Free, I didn't get it free, $100, it has EXCELLENT sideart, but it is a little wobbly, needs some rebuild work at the base or something).
My friend Pat in St. Louis (AKA: Mongo), often has cabinets, many of my games used to belong to him.
Also, check the classified ads EVERY DAY, I have snagged quite a few games that way.
Of course there is also the method of simply checking ebay EVERY SINGLE DAY for local stuff, but that is the most expensive way to go, and way too many other BYOAC members will be bidding against you.
