Along the lines of the recent "collecting" and "price" topics, if I had the reserve price available to spend on this machine, I'd spend it without a lick of guilt. A 420-LSE in this condition is a machine I'd love to own regardless of wether I could ever get my money back out of it. These machines are a thing of beauty to me. Their low production number and historical signifigance certainly merit a higher price than any average production model.
And yes I would garage it and wipe it with a diaper!
