I've never used a ceramic BB, but the ones i see for sale are around $450. The old Shimano cup-and-cone BB in my singlespeed, which used to be my commuter, and before that got the crap pounded out of it as a faux-cyclocrosser, and before THAT was my main bike for four years (it was originally a Trek 620 touring bike) has been repacked once, possibly twice, in 16 years and at least 30,000 miles (wild guess--I don't keep track of milage, but I've ridden it a lot). The last time I opened it up was three years ago, and it looked like new--I just readjusted it and left the old grease in there. It was the standard, came-with-every-bike-in-the-'90s BB, cost 12 or 15 bucks. I weigh 240 and don't baby the pedals, but when i turn the cranks by hand, I can't feel any vibration or harshness.
Which is a long, roundabout way of saying "Money down a rathole." Ceramic is probably better, stronger and smoother, but it costs 10 times as much as a pretty good conventional BB that will go 10,000 miles.
