My FFR was built over a 2 year span in my own garage/shop using all new parts and an American-built crate 351W. I did all the work myself other than the paint. Total cost was over $50k, but it could have been done as well for less.
I am sure there are other brands of equal quality, but FFR's don't deserve a back seat to anyone.
I'll let the pictures speak for themselves. Examine them closely. You'll see the design/build quality.
