We are at 4.00 to 5.00 pd at the other speed shops here in nwa. My friends speed shop has the transfer station for filling 10lb bottles and his cost is around 2.50lb he said and I get it for that price. I have been told by heavy spray users, you can at times get a bottle thats contaminated with solids and by bad gases. I use a micron filter for the n20 before the solonids for the solids. Gas contamination, get a refund.
