I don't post often however I try to read these forums as much as possible. With that said, let me qualify this post. I'm not looking for a business plan analysis. The answer is NO, I'm not trying to make money. If I made some somewhere along the way, great.
I'm a home shop hobbyist guy. I just got done retrofitting a small benchtop mill. For further information see this post:

It was an interesting process but of course now I'm looking for something bigger. I'm considering purchasing a Haas Super Mini-Mill, Super Mini Mill 2, or an OM-2A. What am I going to make with the machine? I have no clue. Most likely more parts for the machines. I can tell you that most stuff I make for myself will be out of aluminum. So as for which machine is the most appropriate, it would probably be impossible to say. It seems the OM series is really suited toward VERY small parts.
On to the subject at hand. I keep a close eye on eBay. Periodically I'll come across a machine that appears to be a seller who is also a home shop machinist or someone that bought a machine for prototype work or small production. In other words, some very nice looking, low time machines. These are very few and far between. I distinguish these from the machines that are obviously listed by large resellers. I'm sure that most machines are sold outside of eBay and that eBay is used more as a form of advertising than anything.
With my limited knowledge I'm wary of buying a used machine only to find out it has some problem that would cost a pretty penny to fix. So, I'm at least considering buying a new machine. My question is, what kind of depreciation can I expect on the machines I listed above? Do some of the models depreciate much quicker than others? My question isn't so much about depreciation over the life of the machine, but the immediate "new car" depreciation that I'm sure is inevitable even with high quality machine tools. Anyone?
