the mystery helmet is really good. it takes a lot more clean up work than the fettpride or bobamaker, but it's the cheapest by far. the master replicas is a great lid... one of the nice things about is is that for the $300 - $400 you get not just a painted helmet, but aluminum ear caps, moving aluminum rf stalk and range finder lights.
seeing as machined aluminum ears and stalk go for $200+ on their own and you'd pay $30ish i think for a light kit, that makes for a REALLY good value.
the visor area has a pinch at the bottom, but its an easy fix.
and you can always strip the paint and redo it if you aren't fond of the paint job.
