I am no expert, but have both RFM and SWE1 I wouldn't give more than $1200.00 for a non working machine, unless you know what the fix is and its simple. if its simple don't fix it there. buy it take it home and do it .
You should be able to find a decent
working machine for under $2500.00, I just blew out my monitor on RFM and its costing me
$350.00 to do a LCD conversion. These machines can turn into money pits real quick
Good Luck
