I am investigating the lead Gav(retropin) gave me, as opposed to going back to the stainless steel company and paying around $30 to $40 a set if ordering apx 12 sets or more at a time.  Otherwise the bloke on ebay is selling a nice set for $99 each plus postage. If u are only doing 1 or 2 machines, that is OK, but for more sets, u have to go to a SS supplier and buy in bulk ofcourse.

Maybe if Gav's lead doesnt work, its just back to the ss company.
