It cost me around $150 to re-head my kit: 20" bass, 10", 12", 14" toms, and a 14" snare. That's two heads each and one 20" bass drum head.
If that's kinda' high for you, I would recommend the Evan's G2's and an EQ3 for the bass then. Double ply heads, and very durable, but they sound great. Depending on how you play, they could last quite a while. But your drums will sound WAY better! I play Remo heads too, but for some reason, when I use white-coated heads, the Remos tend to wear faster and get dirtier over time. Evans seem to stay white longer for some reason.
