I think there are roughly two sizes of this machine, one that is comparable to a Series 1 Bridgeport such as the white one above also for sale here:BedMill
It weighs about 2270 lbs in non CNC form. Was made by Santec (Taiwan) now imported and by Sharp.
Here's mine when it was dropped off all dirty

and then after I took off the CNC bits and did a partial cleaning


Then there is another variation that is more similar to a Series II B'port, closer to the 5000 lb range. If you check the Southwest Industries site link, there are 3 models, of clearly slightly different make than the Santec, one at 3100 with no Z counter balance, then two larger at 4100 and 4400.
