For brushed setups I've used the HobbyWing Quicrun 60a esc. It's about $18 and well worth it. Worked great in my Rustler before I made that brushless, and now over a year later it is performing great in the Arrma while I wait for my replacement. How much was the 35a esc? Seems under $20 is already pretty dang cheap and I wouldn't think it's worth sacrificing reliability or the amperage to save a few bucks.
