Re: Looking for a cheap but believable Indy Fedora.
Wicked. So, the Cracker Barrel hat is more of a replica of the "Temple of Doom" hat than a "Raiders" or a "Last Crusade" hat (I already know that the "Crystal Skull" hat isn't the same as the previous ones, as I watched the making of documentary on the DVD. And I think they mentioned that for each film, the hat varied in style anyway).
Not really, no. If we applied the same standard RPF scrutiny to the Dorfmans, nobody would consider it remotely SA.
As I said earlier, the only thing which makes the licensed hats "Indy" hats (aside from having the license, of course) is that they're brown fedoras.
None of Indy's hats had the teardrop crease on top, the ribbon is a completely different color, and besides the fact that the side dents are blocked on a form, they don't really look at all like the way the hat was creased. There were some shorter Last Crusade hats that
may have been product placement for Stetson. There's been a lot of discussion on Club Obi Wan and nobody can definitively say if any Stetson hat made it into ToD or LC. Regardless, Stetson sells their "Temple" fedora to this day, and is the same hat that was first sold as the licensed hat back in the day. They also now have introduced a wool version of the Temple called the Raider II.
That having been said, I actually kinda like the look of the Dorfmans. But, they are definitely a more modern styled hat than Indy would have gotten in the 30's.
If you want reasonably screen accurate, the Akubra Fed IV and the Christy's Adventurer are the cheapest options.
If you want a brown hat that looks reasonably like an Indy fedora, the Dorfmans fit the bill....although an Akubra will be the more resilient hat in the long run.
Here's my Christy's Adventurer, bashed in an LC Style:


For comparison, here's my Stetson Temple:


The Stetson's open crown height isn't more than 5", whereas the Christy's is 5 3/4. Most of the on screen Indy hats seem to come it right around 5 1/2" open crown height. Note that the Temple comes with a wider ribbon....
