preston811, I've seen those pumps rec. here before, perhaps it was you. I looked at 'em online once and was impressed just as I read now and the other posts.
The 220psi appeals to me. If my Silca doesn't turn-up after having relocted three years ago, I do believe that I'll order one of yours. Over 160 maynot be relavent to the OP or others but I've found them to be valueable fo getting presssure up TO 160 as well as beyond. I'm sure the gauge is accurate as well.
