I've had good results from the SLR Magic Vari-ND mark II, but only when paired with Hoya IR cut, otherwise IR pollution is a real problem.
In fact, the Hoya IR cut is the only screw on filter I've found that completely eliminates IR problems on BMD cameras. There are, of course, some great rectangular ND filters requiring a matte box made a few different companies, but no screw in versions of those. Even the Firecrests, as good as they are, still let some IR through so that black fabric under tungsten light starts to get a bit muddy on BMD sensors.
