As has been noted, this is essentially the same as the PSI 12" Turncrafter, the ShopFox 1218, and a lathe sold in England by Axminister. An obvious difference between the versions sold by these retailers is the color of the paint, but the King Canada version also appears to have a reversing switch that the other versions don't have (although that's an easy add-on). There may be other minor differences that could come down to the relative age of the lathe (ie, the 'model year'). It's made in Asia (not sure if it's Taiwan or PRC).
I've had the PSI version for about four years and have been very happy with it. It's robust, has enough power for most applications within the 12" swing of the lathe, and belt changing is very simple. You can see the advertised speed range in the specifications, but its also possible to tweak the speed settings to give a wider range if you desire; I have mine set to run down to 50 r/min.
A few things to be aware of:
1. It's heavy - > 100 pounds. That's fine in the shop, but it would not be ideal if you are looking for a traveling lathe for demonstrations. It comes in two boxes, and you have to assemble it. For the most part, assembly is simple and intuitive - the only thing that I struggled with is making the electrical connection to the speed sensor in the headstock. I eventually realized that if you open the maintenance port on the back of the headstock, you can easily reach inside to plug the speed sensor cable (duh).
2. It has an indexing feature that includes a spindle lock. However, the indexing wheel is plastic, and while the spindle lock is fine when used for indexing, the plastic wheel isn't strong enough if you need to lock the spindle in order to loosen a chuck that is stuck on the spindle. The wheel is replaceable, and there is at least one YouTube video showing how to do that repair. The picture of the King Canada version shows a hole in the indexing ring on the headstock spindle that you had use to grip the spindle with a tommy bar, and I've seen similar holes on other versions of this lathe. My version doesn't have that hole.
3. The body is a solid iron casting - very robust and quite heavy. However, the bed ways are very slightly wider than the block in the tailstock casting that aligns the tailstock. The result is that the tailstock can rotate very slightly in the horizontal plane (ie, around a vertical axis through the tailstock). In my case, I have less than one degree of rotation, but that's enough to cause a very slight misalignment between the headstock spindle axis and the axis of the tailstock. This is not an issue for most turnings, but it can be a nuisance if I'm drilling a hole in a piece with the Jacobs chuck mounted in the tailstock, and if the hole needs to be precise. I've learned that to overcome this 'wiggle', I need to cut a small dimple in the exact center of the workpiece, and then align the tip of the drill bit to that dimple before locking down the tailstock.
4. The reversing switch (either as shown on the King Canada web site, or as the aftermarket hack) is useful and can help with sanding a finished piece. However, you do need to be aware that when running the lathe in reverse, there is a tendency for a chuck or other fixing that is screwed onto the headstock to unscrew. Sanding, especially at low speed, generally won't produce enough torque, to cause this to happen, but if you want to run the lathe in reverse while turning (reverse turning can be useful when hollowing), you need to make sure that the chuck is equipped with a grub screw to lock it onto the headstock spindle.
