Thanks for the answers!
The milling machines that Lathemaster and Industrial Hobbies deliver looks very good. And these machines are big enough for the jobs I will do with them. But what is the different between a "square column" and a "dovetail column"? The machine from Lathemaster seems very cheap, wath is the price on the machine from IH (I`ve sent them a mail, but havn`t recived any answer)? Since I`m from Norway, I need a machine that can handle 1 or 3 phase 220v and 50Hz. Can these machines handle that? Witch of these 2 machines would you recommend?

Don`t think a Bridgeport will be an option for me, since I don`t need bigger machines than the to others above. An a CNC retrofit would be more expensive on a BP than on a benchtop model I guess. Does anyone know how much a CNC retrofit on a RF-45 clone would cost?

A Bridgeport machine is much heavyer and solid than a bench top machine. But how accurate is the RF-45 clone compared to a Bridgeport (or similar) machine?
