Is there a coat similar to Brooks Brothers Golden Fleece Officer's coat that's affordable?

I'm looking for a coat like this for my bf: http://www.brooksbrothers.com/Golden-Fleece%C2%AE-Officer%27s-Coat/ML00184,default,pd.html

But it's definitely out of my price range but I want the same style... Officier's coat/military coat for bf.

Any recommendations on where to look?

Thanks.
