Not bad for free. I wouldn't turn one up if it was for free. If you were planning on getting a new Dyson and there was a trade in offer on, you could just take along one you got for free that someone was throwing away!
Yes good idea! I once had an Irish DC01, imported from Ireland. Bought it from a carboot sale for £5 and got a free bissell easy vac with it and has NO idea whatsver till I got it home! Nice surprise!
