I just pitched a token bid at your auction, so that it would for sure go on my list. This is an awesome ring and I'll bid to win a little later in the auction. I'm trying to save some credits right now for another auction I'm watching. Are you still using them? If so .... please let me know what you think about them, as I'm currently in negotiations with the manufacturer to become a distributor for the filters, and it looks like it's going to work out. If it does.... I'm like an elephant....LOL..... I never forget...... where it came from.... and I'll offer you an at cost set price for them :) Ron
