My son has one of these:

I've seen him use it, but had never used it myself since I had shaft drive bikes. But I used it on my Bandit this weekend, and have to say it's slicker than $$$$. Without question, it's the easiest to use, and seemingly the most accurate alignment method I've tried. They're not really cheap, but if you've got multiple bikes, or can share the cost with a friend or two, (or just don't mind paying for it yourself) I highly recommend it.
Available from multiple sources, at a wide range of prices:
