It's a good idea to use a tube/jar with speedbleeders too - otherwise who knows where the brake fluid is going to go! I don't use DOT5/silicone fluid, so I have to worry about the paint.
I've had Speedbleeders on my turbo Miata for years, and really like them. Lots of motorcycle guys seem to use them too (I guess when you're using racing brake fluid, you need to keep it pretty fresh).
BTW they sell them direct from
