I would suggest you look at the machines with either a knee (larger size)
or the ones with a dovetail or box column for head elevation (benchtop
size). The ones with round columns lose the X-Y positioning when you
have to change head height.

If you want to do precision work, then a set of ballscrews is almost a
necessity. You can get conversion kits from a variety of sources, or
watch eBay for a bargain.

On the larger machines, servo motors generally offer better performance
than steppers, and may come out cheaper, too.
