Hello Thomas.
The one you were looking at on Ebay is just a common Far Eastern mill drill, still available today in various forms with geared or belt change heads. They work well as a drill, some have quite a long quill stroke which is usefull.
As a milling machine they also work well, but the main criticism is the loss of the head position when raising or lowering the head on some of the types that have a round column. The type with a dovetail column do not have that problem.
If you don't have room in your workshop for a separate mill and drill then these machines are a solution. Just be extra carefully when drilling on the mill that you don't run the drill into the nice tee slotted table.
Although the low cost mill drills from the Far East have had their fair share of criticism over the years, they work quite well and have given plenty of people the opportunity to own a milling machine who otherwise could not. As a second hand buy they can sometimes be a bit of a bargain.
All the best.
