Any experience with RA4 Chemistry with a brand name of Silver Pixel from a large west coast mail order house? I've been a dedicated user of Kodak RA4 3.8 liter kits for many years but am having trouble getting them via internet ordering due to the shipping hazards. My local camera store dealer doesn't stock anymore and he charges me full list plus to special order. The prices of the above Silver Pixel in larger kits is significantly lower than the last two Kodak kits I managed to order. From what I've been able to determine so far the manufacturer is in Michigan so that would be keeping with wanting to continue being a faithful customer of "hometown" manufacturers. Thanks.
