[M100] New M100 owner looking for VDI

[Joseph Grimm]

I recently got a Model 100, and I was thinking about getting a VDI sometime
in the future. Are these units rare? It looks like no one is selling them
on Ebay, so that makes me think they're not all-too-common, and perhaps
expensive. I'm not looking to buy one now, just asking if it is worth the
effort to try to get one in a couple months.
