Dear Lewm: Other that what Geoch mentioned the SX is in another league in the SAEC line this one belongs to the 506/407 top of the line, all these one are build the same and differ only on effective length, all these comes with the 18grs. ceramic headshell. The SX is in between about effective length where the 407 is the shortest and the 506 the larger one.
All the other 308s along the 317 were the entry level that don't include tyhe first rate top of the line quality even comes with different headshell due that the ceramic one was a expensive one an unique to the topo of the line SAEC tonearms.
Lew, as good the SAEC ones the GST-801 is worth to try before and IMHO outperform the SAECs. Of course that if you are entilted with the SAEC SX go for it is a nice tonearm with very good build quality.
Regards and enjoy the music,
