Welcome to TDH Jim. Lots of very knowledgeable and very talented people here - at times passionate too.
The two I have experiences with so far are Wasted Fett and Minutefett. I have FPH2's from both of them and one of the new hero helmets from MF (WF makes his version called the Fugly too). I personally recommend getting either the Fugly or the MFHero helmet at this point. I don't know what the Fugly goes for. MFHero is listed at $450.
My WF FPH2 was purchased around June 2018 for $325ish. I had it painted by Superjedi earlier this year. Excellent quality helmet and excellent quality paint up. It looks like it is now listed at $295. Not sure if that includes shipping or not.
The Minutefett FPH2 I purchased was from earlier this year and was also a great casting, but it did have a tacky finish to it. The MinuteFett FPH2 is listed at $250. Not sure if that includes shipping or not. I bought that during a buy 1 helmet, get 1 half of sale on Etsy so it was even less money and I got a Mando helmet at the same time for a total of $340 shipped. I think I wasn't paying attention and put an extra bolt in the photo below - my bad.
In the photo below, on the left is the MF FPH2 from earlier this year and on the right is my finished WF FPH2 painted by Superjedi. Please excuse the shadow - the sun moved.
I have also recently received one of the new ESB hero helmets from Minutefett which had the same finish as the WastedFett FPH2 I have. The hero helmet casting is MF's best quality I have seen so far.
My assessment is this, MinuteFett is newer to making props. He has made more documented mistakes, but says he will fix anything that isn't right as he is still learning how to do this. I believe his prices reflect this as well and it is worth noting that he has offered a lot of sales. I scored that FPH2 for half off because I bought a Mando helmet. It also helps that he is a nice guy.
Wasted Fett has been making props longer and I don't think I have ever seen a thread regarding him making a mistake. A little more expensive because of his experience and quality control. Also a nice guy when I met him at SWCC.
We all need to try to be nicer and more objective - including me. I like my WF stuff and I like my MF stuff because I like Boba Fett stuff.
There are also several other makers that make quality helmet kits at varying price points, so you aren't just limited to these two. Find someone you like working with, but also don't be afraid to try out additional vendors.
