Currently have a white percelain enameled steel lavatory sink but the enamel
has chipped/flaked off in spots - I don't even think anything actually fell
into the sink to chip it. I would rather avoid this problem with a
replacement and was considering a china or acrylic sink. Could anyone tell
me what the pros and cons are of each of these materials. I would like to
limit myself to a "budget" sink from one of the home supply stores.

Thanks
John
