I know folks around here are big fans of old iron, so I think I know what the response to this will be, however, I'm looking at buying a ~20" bandsaw and have found three different ones that will all work out to about the same price range. The first is the Hammer N4400. The two used ones are 60's era Northfield 20" and a Powermatic 81. Both look to be in decent shape, but I suspect I'll want new tires and guides (and a VFD).

Anyone have any thoughts on these?
