i cloth diaper and do it myself. for one thing, San Diego doesn't have any services anymore. Secondly, I prefer fitted diapers to prefold, and most services only do prefolds. in the long run, it's cheaper to do it yourself. If you think you'll be fine with prefolds, and your parents are going to pay for it, I'd go with the service, though - that way in the early months you don't have to worry about washing.
for little ones, i liked the Bummis Super Whisper Wrap cover. as they get older, I prefer wool covers. you might ask for recommendations over on ther diapering board to get a larger variety, though!
