A few years ago I went in with a bunch of others on a container from someone in Italy (not sure if its the same guy) through a contact here in Canada. Picked up a Road Show and Revenge From Mars for $1500 (CAD) each back when the C$ was almost at par with the US$.
RFM monitor didn't work (which I knew) and cabinet decals were trashed (partly shipped that way, partly thanks to Canadian Customs), some hacks, but otherwise worked. Replaced the cabinet decals, CPU fan, CPU PS, added amp kit for the monitor cleaned and waxed PF and I have $2100 into it altogether.
RS was another story. Rubbers shot, heads not working, fish wear (which I knew), many hacks, cabinet decals shot, etc., etc., etc. Dropped almost $1K into it but it runs like a dream now.
If you're looking for a screaming deal, you may not find it anymore. If you enjoy bringing a machine back from the grave knowing you won't make a profit on it if you sell, tread carefully but there are some good machines to be had.
I'm seriously considering . . .
