I don't know where to buy a media separator in New Orleans, but Corral Connection in Kenner has a bad ass casing sorter operation in the back. Hammer (I don't think he posts here anymore) took me on a tour and it was quite impressive what they were doing with home made equipment.
althought, Jefferson Gun has the Dillon separator, I like the Cabela's one, that's actually made by Berry's Mfg, and i think the same one RCBS has, and it's only $29.99. but you'd have to make the ride up there.
Any ballpark idea of what the dillon one cost? I'll give them a call before I head over there. I may just have to order one online, the trek to gonzales won't be happening anytime soon.
