MM,
INFI is great steel (for bombproof hard use choppers). I don't see a reason to pay for the Busse name on SR77 or SR101 though. The best excuse is to have another ASH, but honestly I'm not sure it would be worth the premium "BUSSE" etching will fetch.

I've had over 200 Busse, Scrap Yard and Swamp Rat (probably closer to 250).

Busse INFI is great for choppers.
ScrapYard SR77 is great for choppers.
Swamp Rat SR101 is great for everything else.

As a user / non-collector I don't have interest in anything else.
