You might have good results with an older bow made before steel strings were invented.
The clip below is something Andrew Goodlett sent me after I sold him a circa-1850 "transitional" bow, made after the Dragonetti-style bow but before the advent of the modern German bow.
As you can hear, he draws a wonderful sound out of gut strings, and I see these bows change hands for between $200 and $500 when they pop up on the market.
As I recall, the bow was heavy and chunky and drew a lot more sound out of the bass than did my pernambuco Siefert German bow, even with the thin ribbon of hair that was on the old bow when I had it. http://www.youtube.com/watch?v=Ee4DU4Qnt7Y
