OutdoorKing Repair Forum Forums Finding and Swapping Idle Chatter Buying an old mower: How much is too much ?

Hey guys,

Always on the lookout for older and interesting mowers, unfortunately I don't really know anything about (older)mowers.. their history, whether they're rare and worth doing up.. expected price to do up.. expected sale price if choose to sell & at least make money back etc..

Is there a general rule-of-thumb when working out how much to spend when buying an old run-down, non-running, needs-resoration mower ?

One in particular is the VICTA 18.. came across one on Facebook, asking $50.. though have read others picking up these (& others) from Recycle centres / tips for $10 .. is it worth the $50.. or too much ?

Sorry for the small pic..
