$250 is definitely not in the budget right now so I didn't get too many details. LBS said that the ceramic was an upgrade in that there is less power loss through the ceramic bearings. I believe he said up to 10 watts per hour. According to this link (
http://en.wikipedia.org/wiki/Bicycle_performance) an amateur racer might generate 200 watts per hour. So, maybe a 5% reduction in power loss due to bearing friction? We didn't even talk brand name, so I wasn't even aware that there are lots of different makers of BB30 bearings.
I haven't been able to find too much info online, but I have seen a few anecdotes that say the ceramics don't last as long.
