I've had two cranksets from them and a chain guard.
Both the cranksets were packaged apallingly; one got away with it, one arrived with a load of damage from the arms smacking against each other during transit. S&L were receptive when this was reported and offered an acceptable-if-not-stellar discount, although I'd rather have had properly-packaged, undamaged bits.
Also it was clear that the cranksets had been removed from bikes (no retail packaging and some witness marks from pedals); which wasn't entirely unsurprising given their price, but not disclosed in the ad.
