Turntable guys... Need help with Stanton 681EEE

I have been away from vinyl for a very long time. Since my stylus started sounding horrible, and I just stopped using the format altogether. I am thinking of having another go 'round, what with reading all these vinyl die hards :)

Anyway, I have my old Technics SL-1600 with Stanton 681 EEE, and I want to replace the Stylus. Does it need to be EEE, or would an E be the same? I have a bid on an E on ebay, and I have no clue what I'm doing! Please advise me fast, so I don't buy something wrong or can't use. I am feeling "young and stupid" all over again... but without the young :(

Also, what is the correct # for the Old Stock styli for the 681EEE, as I understand the "New" replacements are nor nearly as good... at least from what I have read? Any info on these is appreciated!

Thanks Guys
