It depends what you want to do. Those round column mill drills are pretty crappy for milling. If you will use it mostly as a drill press with the occasional milling job it should be fine, but if you already have a drill press and want it for milling I wouldn't waste my money.
At a minimum I would look for something with dovetail way box column (not round). At least then you can raise and lower the head without losing X and Y position.
This machine is small, but will function better as a true mill for a reasonable price. Just make sure the work envelope is big enough.

If that one is too small, then you might move up to something like this. Same basic size as the one you posted, but with the box column/dovetail ways.

By the way, I'm not recommending Grizzly. They just have a nice website with pictures. Most of the same machine can be had in other paint colors (Jet, etc.).
For what its worth, I started out with a Rockwell milling machine. It is small and compact, but is a true knee mill. Like a half size Bridgeport. It was a good machine. Much better than the imports I listed above, but still light duty machine.

My next machine was/is a Deckel FP1, which is fantastic. Small, but stout and extremely versatile. Unfortunately they are somewhat rare and expensive.

Best bet really is to get a used Bridgeport or similar. You can get a decent one for the same price as the mill drill. Tooling is cheap and available everywhere. They do take up some space however.
