It is summed up in the last sentence: "I’ll choose magic, if only it didn’t come at such costs". And that sums it up - everything Dyson is a major investment.
About the most affordable, and something I bought for MrsS, was a Dyson Supersonic hair dryer. It is still not cheap, but is is quiet, powerful and light. But would I spend three times that for a Dyson vacuum cleaner? Well no. I've just fixed our twenty year old Sebo with a new mains lead from eBay (the old one was chewed), and some duct tape over a hole in the base. It does the job, and the green thing is to keep it going until is really does keel over.
