The Bader III is definitely a fine machine. I just went through the process of deciding on which grinder to buy and have looked at, considered, contemplated and priced out just about every grinder on the market. The Bader will come in just north of about $3000. I wasn't sure I wanted to spend that much on my first grinder so my choice came down to 4 machines which all priced out in the $2100 to $2800 price range. These were, in order from lowest to higher priced, the AMK-77, the Esteem, the Pheer 454, and the Northridge. I initially thought I would go with the AMK grinder, but considering it was primarily light weight aluminum construction and used a motor of dubious origin, I changed my decision and today sent a check to Brett Mathews, the builder of Esteem grinders. This is a solid machine, steel construction with a 2hp American made Leeson motor and variable speed drive. It also comes with, in my humble opinion, one of the best standard work rests available for any grinder in its class. The Pheer grinder is also a good grinder and many here own one although it will cost a few hundred more than the Esteem. Northridge is a startup builder of grinders and they also have what appears to be a nice machine. Options for it however appear to be a bit pricey, and it topped the list in terms of price for the options I was looking at. Another important aspect is customer service. All of the grinders mentioned so far in this thread have builders that stand behind their product and are quick to assist with any questions that you may have.
I should point out that I priced all grinders with a 1.5hp or 2hp motor, variable frequency drive (VFD), Flat Platen, Contact Wheel, Small Wheel Attachment, and a Tilt Base.
One other thing to consider, and I've been told this by a few builders, is that prices will be going up after June 1st due to more stringent federal regulations kicking in regarding motor efficiency. The difference will likely be in the neighborhood of about a $75 increase or so according to the folks that I've talked to.
You've definitely come to the right place to ask your questions. There is a wealth of knowledge available here and a strong willingness to help others that are just starting out in knife making. Good luck in your decision. Your husband, however, obviously doesn't need any more luck.
