Colin (lizard931 on Rennlist) is in Abbotsford, BC and is the distributor for JDS repair (
Bosch LH 2.3 ECU Repair - JDS Porsche) in Canada.
He should have the rebuilt unit in stock for $450 (I think) and you would not need to deal with customs plus save some $$$.
If you want his contact info just PM me.
