Personally I don't think you can go wrong with BobaMaker, I own a full suit including the helmet from them, its great and got a lot of compliments at Star Wars Celebration Japan the other week.
WastedFett or BobaMaker are both great options for cold cast un-dented helmets. Cruzer used to make cold cast dented helmets but MinuteFett now owns his casts. MinuteFett stopped making Jango helmets a few years ago but is currently working on getting them back into production - If you need a dented helmet then that is your best option at the moment.
I have a BobaMaker and a Denuo Novo Helmet. Both are almost identical. Denuo Novo was scanned from a helmet that was used in the movie. Also, from what I recall WastedFett and BobaMaker have molds from a Legacy helmet from back in the day.
