I assume that you're a hobbiest like myself. So a few questions need to be answered:
1. How often will I use my mill? If not daily, consider a used mill.
2. If I ran into hard times, can I get most of my money back if I need to sell my mill? A new mill is an instant money loss.
3. Is buying a mill for my hobby? If yes, get the BP. The "feel" of a vintage machine is much more satisfying than a new one.
Times are still tough. There's a lot of bargains out there. Currently they're 2 BP mills on my local CL, one for 3300$ & one for 2500$.
Also, I bought my 1938 Cincinnati combo mill in a pick, for a lot cheaper than a new Jet mill. What's great about my vintage mill is that it's a hoot to run, and it makes chips the same as a new mill.
I'm not saying anything against the Jet mill. I like to use the late model one at work. My advise is to consider the long term financial consequences for yourself.
Please write a follow up post on what you buy.
Happy Trails!
