That's the "big" motor with a MT3 spindle. There's a smaller motor that can go on the same base, but it does not have the torque. The big motor will power right thru 3/4-10 taps in A36 steel. Its a load but could do thousands of them as far as my opinion goes.
It also has the "fine adjust base". If you are trying to drill a hole into a sidewall, getting an 80lb tool precisely aligned and then applying the magnet is an exercise in sweat. With that system, one gets "close" which is probably within 3/8" of center. Apply the magnet. Now loosen the crank in the back and the two parts of the base "float" relative to each other slightly. Little taps and checks to get it exactly where you want it. (Theoretically one could put a dial test indicator and sweep out a bore) Then tighten the crank and start drilling.
I have been involved with them to make "machine tool accuracy" mods to big stationary pieces of equipment. Essentially a guide plate is made in an actual shop with hardened drill bushings and bolted to the piece of equipment, usually keying on existing features. Then the magnet drill gets setup, sweep the drill bushings if one really cares but usually the tool will let you know. Once the center location is established, pilot holes, taps, and reams for dowels can all be accomplished in the field. There is a gib to take up play in the dovetailed slide.
Imo sounds good on price. I would worry like hell about shipping though. That thing needs a plywood crate surrounded by a thin layer of cardboard. Heavy boxes get abused (meaning tossed) in ground ship.
Also make sure to remove the handles (they screw into the center hub).
I used it recently to make some mods to a press brake frame for a crossbar that made rigging/moving the machine a snap with a relatively low ceiling.
Previous uses were tapping holes in this ~400 lb bench from a radial drill...the frame is solid 1"x3" steel bars.
Drill & tap holes into a 1" thick A36 weld bench...
A few holes in a structural I-beam for the shop expansion....
If you have "big and heavy" stuff it will eventually come in very handy!
