50 watt amps in Australia?

Hi, first post here so apologies if I've overlooked something. Thanks also to Steve for the guidance in signing up. I have a couple of early MM 210s (a 65 & a 130) and am interested in finding one of these small (and lighter I hope) 50watt amps. Do any Oz MM fans know of any available? Which model should I try to get? Is it feasible to buy one from the US or Canada and put a 240V power transformer in it (Mojo seem to carry them)?
thanks all,
Sam.

Sam, There's a RD50 on e-bay, in Newcastle NSW. Price is low.
