Been pricing headstock steering stem bearings for my Greeves. The first seller wants around $60 for the pair, more expensive because they are Imp not Metric. Next gave me a discount total $50, so I tried a seller from China $4.99 US each plus 99c delivery for the pair, total of $10.96 delivered to the door. If I buy a similar Chinese bearing from Australian seller they are around $12 each plus delivery. Not suggesting that you all go out and buy Chinese stuff but the price does come into it specially in lower impact and load situations, not for the likes of main or wheel bearings.
