The fact that you refer to it as a Mill / Drill and the pictures that I found on line in a search tell me that this is a typical round column Mill / Drill similar to the RF30. That being said, what condition is it in? Has it been used a lot or has it sat in a corner? The biggest thing to keep in mind is the fact that the head can rotate out of position during a heavy cut, if you don't have it cranked down tight, and the only vertical travel you have during a set up is the quill travel, which may be from around 3 1/2 to 6 inches. If you have to move the head up or down during a set up, you would have to indicate it back into alignment when you lock it back down, and that could be a little tough. I bought one at an auction and have played with it a little and will probably see if I can sell it some day in hopes of getting a larger square column on knee mill. You also need to check to see if it uses R8 or MT taper collets. A new Grizzly of that style runs about $1400. I am a novice, so you might want to look around at the forum for anything on the RF30 - it will most likely apply to the Jet 16 as well, at least in general. I can say that with the belt drive and a 2 HP motor, it won't lack for power. Does it come with a stand or any "extras" like collets or a vise? It will most likely have 5/8 Tee slots, so you may not have hold downs or bolts suitable to mount you vice from a smaller machine, so those might be things to consider as well, if they aren't included, since they would run the cost up, if you don't already have something you can use. Just my two cents worth... You might also post this in the Jet, Enco and Rong Fu forum......
