I went cheap and "generic" (not custom molded) with the Hearos High Fidelity models. They are up to 12dB of cut. IME they are great for preventing ringing and volume fatigue for me afterwards when practicing in a small room standing next to a hard hitting drummer on a strong acoustic set. And guitars/bass/vocals set to appropriate combat level.
Yeah those Hearos plugs are hard to beat for $10. Not perfect by any stretch, but much clearer sounding than disposable foam plugs.
