As noted, it's a cheap import, sold under a dozen different names.
However, somebody's spent some time upgrading that particular one. It has a keyless chuck, and the motor's been replaced with one that looks to be of better quality.
One might presume that if the owner went to those lengths, he may have upgraded the bearings as well.
However, keep in mind those things are tiny- note how little "daylight" there is between the tip of the drill bit and the table, and how low the table already is on the column. If all you're doing is drilling sub-3/16" holes in flatbar, go for it. But if you might want to drill a hole in something that actually has some thickness, you'll run out of room in a hurry.
