I hate to give the big auction site more advertising, but there's a Beseler 45MCRX on there, located in Mt.Dandenong, with no bids on it, at the moment...

As for advice on the best 4x5" enlarger - well, after going through several of them, my fave is my current one, a DURST AC1200 (variant of the L1200) by a country mile - stable, easy to use, beautifully made, etc.

Marc!
