the BEST custom drum company is Dunnett. Ronn Dunnetts snares are top notch. I love my good old supraphonic, but if you really want somthing differnt, Dunnetts stuff is amazing. He is even working with ludwig on the stainless steel reissue kit, and making the titanium snare for Ludwig.
Dunnett has made drum shells for every big drum company and every big drummer, Carter Beauford usally has his purple and gold dunnett in front of him, and Stanton Moore has his dunnett titanium on his gretsch set.

For the money, nothing beats the supraphonic. Every one needsa Ludwig Supraphonic snare in there arsanle. But once you have a supra, and if you want somthing differnt and special, theres no better custome drum than Dunnett.
