Jeez, I live in upstate NY. I have never seen a LV casino chip at a garage sale around here. NEVER. Not even common ones. I see a chip here and there at the largest flea markets, but even then, it is slim pickings.
Without eBay, I can't collect what I want. Period. I try to keep it all in perspective. I would like to see a little competition, so eBay is forced to play nice, but the bottom line for many collectors is no eBay=no collecting.
