problem with sanding at home is obviously time and patience, both of which I don't have. So you end up rushing and cutting corners and telling yourself "that'll do",and, if you live with a cleanliness freak, the dust and mess generated will drive her (or him) nuts, which will of course will come back on you. By the time you've finished doing it yourself you'll probably have ended up spending a thousand bucks on sand paper, strippers, chemicals, tools etc etc.
