I'm torn between an Industrial Hobbies square column mill and a knee mill, either a used Bridgeport, or a new higher-end import like the Birmingham. My key requirements are a minimum 12" Y travel, and variable speed, since I will immediately CNC it.
So, the question is: What are the relative pros and cons of the two types of machine? If I buy an IH, will I later wish I'd bought the knee mill?
I'm going to ask the same question on the IH forum, so I get both sides of the argument.
