Centre stand is the way to go. You can do everything you'll ever need to do with one, even the swingarm and forks, together with some strops to hold the rear/front of the bike up in the air from the rafters. The only real advantage of a bike lift is it will save your back as you don't have to bend down so far to do the work.

I had a bike lift, but sold it a few years back - didn't use it enough to warrant having it. The big problem with them is that, on the 360 days a year when you aren't using it, it'll just be getting in the way, taking up valuable garage/shed space and you'll just be tripping over it all the time! The other disadvantage of a bike lift is you can't take it with you on a trip - a centre stand will always be your trusty companion, where ever you go.
