You would be much happier with a square column bench mill than those round column types.
For instance, once your setup is complete and you find you need to raise the head, it swings out of position, then it is back to setting up again. The short stroke quill makes that even more of a pain when trying to maintain spindle alignment and differing cutter lengths.
The round column type heads are also more prone to shift while cutting, IMHO making them a lighter duty machine with a higher probability for unexpected cutter grab, limiting its capacity to keep it, the part being cut and the user...... content.
The money you save may test your patience, the fuss is somewhat expected for the budget territory. Sometimes something is better than nothing. When you have experience on industrial scale mills, trying to use one of these round column bench mills is beyond frustration!
