Well I've got a Hobart Hood, which is great. It's solar powered so the welding flash recharges it as well. I'm pretty sure most of the "face painted" helments are a Hobart Hood or various ranges.
I had one of the "cheaper" versions and I found that the darkening was too much even on the lowest settings, couldn't see the work properly. Make sure you get one that you can easily replace the perspex lense covering, becuase you will fine they get dirty pretty quick, especially if your using gal pipe or welding upside down
Also look for a nice big lense, other wise you may feel a bit like Ned kelly.
