I see them on Craigslist and wonder the same thing. For the longer term, I wonder whether there are parts still available to rebuild the shock, but I haven't tried to research it since there are other bike options/choices, so haven't invested the time.
An artist who rented one of my studio's in Crested Butte did that paint job years ago, never saw the bike built.
I like your thought as I am a fan of the AllAxle but not sure it is the best application for that bike? Really depends on the OP's intended use as a mainly road type bike or for trail use with lots of climbing? If the latter is the case a TSDZ2 and a Hailong battery for around a grand all in would do the trick.
