Has anyone ever found a website with what might approach a comprehensive list and description of milling machines? This is a tall order, and for that very reason I'm looking for one. I'm in the market for a used mill, but I find that I keep turning up more and more models that I don't know the spec's on (read "more and more" as "99%"). If you're looking on ebay, many of the sellers don't provide a detailed descriptions... And as much as I enjoy it, I spend a LOT of time googling the various models then getting distracted by whatever other machines are at the site...
