Paul,
As a fairly new collector, I have a pretty small list of traders. Most are not in new condition and they're all pretty common. I also don't make it to a casino more than once or twice a year. Since I'm just starting out, I prefer to use the extra chips I have to trade and build my collection. However, I am willing to sell my traders at face value plus actual postage.
I was hesitant to respond to your initial post because I am rarely going to be a good source for new chips due to my location (southeastern New Mexico). I have started picking up extra chips when I do visit a casino, but it's not a frequent occurrence. So, if I meet the criteria you're looking for, feel free to add me to the list.
