I want to make a quick survey of the best buy in single speed, bmx style freewheels.

I was pedaling thru a snow storm yesterday going uphill when I heard something like a chain skip (a very rare thing for me, unless the chain is really worn)...
a couple of meters later i find myself pedaling and not advancing. Something was broken in the freewheel i've had for only 6 months...

It's kind of a bad feeling. I could have crashed hard due to the surprise it caused. I was alerted by the weird noise (and see my chain was still on) so I swerved on to a less busy street.

I'm looking for a quality replacement. Any ideas ?
