peanuts... but i was in a more fortunate position than you as i wanted a 220V model 30RZ (we are 230v/50hz here - so the 20RZ would have been a bad choice of pump...) and luckily find a US seller with a WMD-30RZ -220 who (in theory) wouldn't ship outside the US - and hence had no bids after several days.... and could be persuaded to ship to me if i bid - so i was the only bidder
- he had 2 to sell so i took both.
shipping of course was a lot (they are
heavy...)
basically the non-threaded version of this (mine was even cheaper
)

(obviosly you could get one of these i suppose, though you'd need a voltage converter too... and to be confident your setup can take the 15.5psi it generates at 60hz!)
