When I think of vacuum tools I think Mityvac. Its made of plastic but its built tough. It definitely has some suction and works great. I like the throttle lever at the top since you can vary the amount of suction if you so desire. One thing I don't like while bleeding brakes is that it sucks so hard it pulls air from around the bleeder screw. I am told a little silicone grease around the bleeder will fix that but I haven't tried it yet.
