WOW.....Under $1000 with free shipping, 1hp DC motor, variable speed with low of 50 rpm (don't know about torque at that speed), and a 38mm spindle bore!

I've been using an 8x14 Lathemaster (no longer available) for about 15 years now and a couple "issues" (for me) have been the too high minimum speed of 150rpm (hard to thread at that speed and cutting grooves in steel it tends to chatter) and small 20mm spindle bore (tad over 3/4"). The small spindle bore does present issues when working with 1" diameter stock I often use. Seems that the lathe has metal change gears (similar to my LatheMaster) instead of "plastic gears" that some small Chinese lathes are fitted with.

I did find that my Chinese LatheMaster worked OK, however when I tore down the lathe and lapped the sliding parts using a surface plate and dye that the fit between the sliding parts was very sloppy. Simply lapping (really not simple or easy) the sliding parts reduced cutting chatter considerably.  Don't know about the quality of the spindle bearings "Spindle Accuracy: 0.0004-0.0012" (0.01-0.03 mm)" but spindle bearings can be updated if necessary (did this with my LatheMaster). LOL....0.0004" is really good but .0012" not so much.

that spindle bore is a masssive plus.. the next cheapest at 1.5 inch is the bolton 12 by 24 for 2000.
