I have a Dyson DC08 that Dyson said was "far too old to get parts for, but we can sell you a new vacuum cleaner!" I don't know much about fixing electrical goods, but the instruction videos at VacuumSpot were really clear and they could still get a motor for the DC08. Took a little while to get the motor, which is OK with me, and the DC08 is now roaring away as good as new. Great service and instructions.

Approximate cost: $120
