Which knife are you refering to?
I think that some of the Bark River offerings in A2 will be a nice replacement for the mean street or possibly the badger as well.
For the badger, it's a little tougher, maybe something by Trace Rinaldi, like a thicker tactical kitchen knife. I don't know how close you're trying to get either.
And for the others, Steel Heart, and Battle Mistress, there's TOPS knives, Ranger knives, and Fehrman knives, with Fehrman using the best steel out of these, 3V.
BUT if you look hard enough, and are willing to pay the $$$$, there are still A2 Busses out there to be had, and INFI versions of the same knives which will actually be cheaper, even though the steel is better (in my opinion).
