I highly recommend the Craftsman Motorcycle/ATV jack. It's cheap (about $100), solidly built and is rated for something like 1500 lbs. This is my first time using the jack so I was sweating it a bit. Finding the best position under the frame was a challenge so I have included a few pictures so show specifics of where I put those jack pads.

USE THOSE STRAPS. I'm not sure if you can tell in the picture, but I ran the front strap across the frame backbone just in front of the tank. I removed the seat and put the rear strap under the seat mounting tab. The Craftsman jack included a pair of ratcheting straps with rubbercoated hooks. The jack also has 4 places to use these hooks at all four corners. When removing parts on the front, rear or either side, the weight shift could be a problem. Potentially, torquing a stubborn bolt could even upset the balance. You should always be careful, but using these straps makes it a lot harder to have an accident.

As per the instructions with the jack, never rely on that bottle jack to keep your bike safe. When you lower the bike, even with the jiffy stand down, the bike may settle to the wrong side and you'll be a sad, sad person. The jack comes with several safety stops. Engage that safety bar and then lower the bike so it engages. It's like using jack stands. The jack was just for getting it up there, not for keeping it there.
