I'm in Canada too and have been watching for a sale on a scissor lift. I had a four post lift in my old place, but it was more for storing a vehicle. I hated dealing with the posts all the time, and as a previous poster mentioned, the four post is good for storage and only a few other things. I used it for oil changes and even wheel alignment on my race cars. But it was a real PITA for anything else where you need to remove wheels (i.e. I couldn't use it much for working on the car).
I picked up one of these last week and am super happy with it (Herkules L1200P):

It has a clearance of 4.6 inches, which is OK for my current vehicles. Can always drive up on boards to provide some more height. I got it for $1700 (CDN), which I think is a good deal. It's air operated, so sits a bit lower than other scissor lifts. I figure if I need to work on exhaust or something central (very rare), I can use it to put the vehicle on jack stands. It's got a nice flat surface, so can also be used for a table, if I want to put it in a corner of the garage. It moves around quite easily, but it is extremely heavy, so would not be able to put it leaned up against a wall. I just put it under where I park my truck and I don't even notice it (way less intrusive than a 2 post or 4 post, but I do park my truck in the garage all the time).
Anyhow, I know it's not the same as the one you are looking at, but can be used for comparison.
Cheers,
Rod
