My two 12" Schick tonearms have no anti-skating.
I've owned one, nice looking, but relatively cheap tonearm from a DIYer, designed for SPU and Denon 103 (both with conical tip). All new versions of the Schick toneams now have anti-skating!
If you want to save your records and stylus tip you have to use anti-skating.
Actually Schick arm is the only one without anti-skating out of at least 10 very nice tonearms (vintage and new) i have tried.
I think that statement that the sound is "better" without anti-skating is an urban legend.
