It is a mill, not a drill press, they just have a drill chuck in the spindle. They are a good small-medium size mill, popular for small shops. Not a Bridgeport, much lighter weight (weighs 1/4 to 1/3 of a small BP), more comparable to something like a Precision Matthews PM25.
If you have the room for a Bridgeport, it is hard to go wrong with that choice. You will get a lot more mill for your money. I say that as an owner of a Clausing mill.
If you don't have the room, or simply don't want to deal with a mill that big, these Clausing mills are very nice if not abused.
The typical price on these is $2000-2500 in good shape, less if it has issues. $3000 is higher than I'm used to seeing, but prices are going up on everything. As always condition and included tooling is a major factor.
Looks like this one has the optional column riser with is desirable, adds an additional 4" under the spindle.
