I just paid nearly $200 for my tan 301A about six months ago. The seller said it was in good working order (which it wasn't) and it didn't have any accessories except for the case (which smelled to high heaven of grease which now I've heard is characteristic of those cases). I ended up getting it serviced where I work in Glendale and the final result is that it does work very nicely but has a rattly sound which I don't even hear any more and doesn't affect the working of the machine. Our tech could fix it but I've decided it's not necessary, probably a broken fin, or blade, on the cooling motor.
I'd say if you could get this one for $100 to $150 it would be a deal and still worth it if you needed to invest another $50 or so in it. IMO... it's very pretty and mine plows through lots of heavy thicknesses.
