I am a many year 3/32" drive train adherent. Most of mine are Surly and Soma which are kind of a step down from the really good stuff. But if their $30-ish price is still high for you...I won't insult you with a "Let Me Google It"...meme but that is my answer. There are tons of lower-priced "consumable" types of 3/32 cogs out there if you just search. Good luck...
