If money is no object go for it. But there are so many perfectly working 500 and 501 out there for so much cheaper, I mean WAY cheaper, what is the point? Even ones with recent overhauls by very good technicians. These are built like tanks, even well-used will still work perfectly for many years. Heck get two for less than half and have a back up. I did that with a 500CM and 500C about 5 years ago.....I've never even used the C.
