Which starter helmet?

Well thanks for all the advice, guys. I just bought the Lost season 1 box set, so I'm not gonna be spending a lot of money (or doing much of anything other than watching it) in the near future! But I'll let y'all know when I finally get a bucket.

Ok, get this:

I stopped by the costume shop today (they had the new full-size Darth Vader costume on display, AWESOME!!!). Someone bought their Rubies Jango, but I pulled the DP 97 Boba off the shelf to check the price and they wanted $69.99 for that POS! So I decided that I can build one that looks a lot better for less than 70 bucks, and I'm scratchbuilding! I'm using a Rawlings helmet for the dome, Forced Trekker's face template, lots of Kripps' ideas, and TK409's mystery measurements. Wish me luck!

Doing a little thread mining, and I hear a lot about the Marrow_Sun helmets, yet I can't find much info on them. The info I did find seemed to say that the MS buckets were a small, limited run. Is this true?
