Thread's getting old, but still..
I used one of those HF lifts for 2 years. It works great for everything but dropping the oil pan but you still have to figure out a way to chock the front wheel and do a 4 point tie-down once you've gotten the bike up otherwise it's not safe for anything that requires any torque, which is everything. I used a big sheet of 3/4 plywood with 2X4's screwed in. You can see a pic here -- search for my handle 'motorhobo' and you'll see my pic:

For a chock, get the HF motorcycle wheel chock for under $50. But a moto lift is big, heavy, expensive, and takes up a lot of space. If you're only working on bricks, they don't require a lot of maintenance and my moto lift sits around 95 percent of the time. I also used the good ol' sawhorse as shown here, but I prefer the HF moto/ATV lift over that.
With the plywood and ATV lift, I was comfortable with the stability with the bike a foot or more off the ground. No matter what lift you use, you'll need to do a four-point tie-down, even a moto lift needs that. The ATV lift sure isn't the perfect solution but at least it rolls off into the corner of the garage when you're not using it and the plywood is flat enough lie on the floor and not bother anything. The moto lift in my garage is a pain in the ass most of the time and if I move I have no idea what I'm going to do with it.
