Do you run gears of single speed?
I use a DMR Revolver s/s hub with an ACS freewheel on, 36 ep's strong and has not skipped since I got it while riding trials, just one or twice riding along, it was loose then. Since I locktited the lock ring up it hasnt even done that... Pretty cheap combo too, less than £50 and reliable.
Edit: Chain Reaction Link for the hub and Tarty Bikes for the freewheel.
Works out at £44.50, think that all includes postage...
