i've got a badger anthem, and i'd say it's a good starter dual action brush. other than that, i've used the paasche vl quite heavily and have always been happy with it.
back in the early 90s i had 4 of them, and never had a problem that i didn't cause myself (like dropping it or similarly dumb things)
the cups are tricky, since it's really easy to spill you paint. jars will cost you a bit more, but it's worth it.
