Lucy said she was disappointed with the Dysons - I wasn't, the DC07 and DC14 are still very common, there are loads for sale on ebay, to the point that ebay is saturated with Dysons.
However, the early models, like the DC04 will do better, and DC01/DC02 doing the best.
Lets see how much the DC01 will make - I think that will go for a small fortune. ALso bear in mind that old Hoovers are very sought after - they have a lot of fans, and some museums may even be interested in some of the older bagged cleaners.
Alex - I tried hard to drum up support for the auction - I wanted Lucy to get the best prices for all her stock - it owes them a fortune. She actually thanked me for putting the word about. Maybe you'd be better sticking to the second hand £30 max cleaners that are local to you in Manchester - you've done alright with them up to now.
