If the molds have been updated, he's either made new changes to his older recasts or recast someone else's helmet again. And you cannot be sure you'll receive if you order one - it's pretty hit and miss, so buyer beware.
The cheaper helmets are usually bad recasts, so you get what you pay for. Though, there is one cheaper option, but it is a fan sculpt and is sold by Bookface - he offers a few different versions, but if you have to go cheaper, then he's your man. If you want to spend a little more and get stuff with direct lineage, there's Mike Warren / vadermonkey.
Mikes ROTJ and ESB are only $900 and far superior to anything SFX put out. I currently have a ROTJ helmet and armor on order with Mike. I recommend that over SFX.
