Keep your eyes out for used commercial equipment. I came across a Fleetwood 10" slicer that was "broken" for $40. Turns out that the only thing wrong was an out of adjustment safety switch. Lucky snag! I am looking around for a grinder/stuffer.
I have to agree with the buy the best you can find attitude and going the used commercial route I think is actually an advantage. Alot of the nuts, bolts, knobs, belts, motors and such are actually eaiser to find on the web and are often off the shelf hardware. Almost all castings can be repaired if you can't locate a factory replacement and to top that off alot of commercial stuff from different makers is really "rebadged" stuff from two or three major manufactures!
My next project is cleaning up a Vulcan double basket deep fryer that is about the nastiest thing that I have ever come across. Looking for the best degreeser out there. I have heard of a dry ice or nitrogen cleaning process but haven't really looked into it yet.
My wife asked why I brought home a nasty, greasy deep fryer and set it in the drive way. So I told her that I was gonna train the kids to get a job at McDonalds
