But its a tilt column.Harbor Freight makes a decent square-column mini mill. They have 25%-off coupons a few times per year.
Personally if I was going to buy such a small machine I'd buy the one of those Little Machine Shop offers with a fixed column instead of a tilting column. The reality is even for its size its much more rigid, and most people never really need to tilt the column anyway. Sure you might have to tram it like any inexpensive machine, but once trammed it stays trammed. They can just tilt the work piece in the vise. While sure they cost more than that machine in the ad, they are more machine.
I can't believe I was just arguing in favor of a mini mill. Any mini mill. LOL.
