I loved doing the DC07 refurbs, but work commitments meant that I cant do them any more, and there wasn't really that much money to be made doing them, but it was enjoyable nonetheless. The market is flooded with people who do up old Dysons now, and prices have come down what people will pay for an old Dyson, so if you do it for a hobby then that's OK, and I hope you build yourself a nice DC07, but don't pay over the odds for bits, because you are young, people can and will take advantage of that, especially at a Car Boot Sale.
