SME Needs good Head...

anybody having experience with after market head shells for SME arms? (pros/cons) I understand a carbon fiber product is available. But I'm having trouble finding a vendor for one.
How about a NOS SME headshell? And then there's always the $39.95 Sumiko with azimuth adjustment and high quality leads, available at Music Direct, Acoustic Sounds, and other quality-oriented online vendors.
thanks for the serious reply's... LOL
all i'm trying to do is find a suitable replacement "HEAD SHELL" for my SME 309 arm. Granted the pun was intentional, However i could still use some direction on this Q
thanks in advance
