No idea on the Kasuga but the FE is a nice one Last year I bought a model F (same gun w/ extractors) from Cabelas but returned it after seeing it was off face. It was plane-jane but a nice quality gun, perfect for the field.... handled nicely and was light.

There is another for sale on line for $2750.

Here's a pic of the one that I bought. Is it the same as the one you're looking at?
