Since I'm fairly new to collecting, I haven't dealt with that many NISs. The ones that come immediately to mind are Josh at Dice702.com, Pete/Chantal Rizzo at www.oldvegaschips.com and Andy Hughes at www.nevadacasinochips.com. All have offered very prompt service, follow-up emails and quality goods. When I'm looking to buy new chips, that's where I've gone and have never been disappointed. I've also bought chips from others that post on this board and they too, have treated me fairly. The few times that I felt I received less than I paid for did not involve anyone here, but a couple of eBay sellers. But then again, I didn't HAVE to bid. On the whole, I think I've been very lucky.
