I'd love to see the ones you've found! So far, I have found exactly one. On ebay, it comes with an R8 collet chuck. $225. The same company used to have one that came with a 3-jaw scroll chuck, but they're out of stock and have been for a while, and no idea when they'll get more. Chinese, but ain't they all anymore.
I think I'll do like the savvy boys do and make one. I don't know how to thread, so I'll weld a McMaster nut to a slab of HRS and carve my own. I have access to a mill at work, I'll gouge out some slots and make a 4-jaw of sorts, that'll at least get me started.
