True Chris,
A Kirby, Filter Queen, or a Rainbow costs upwards of a thousand dollars US.
However, when our daughter purchased an Electrolux Oxygen 3 cylinder for $500 in 2010 that was a lot of money to them, as they were just starting out. It only lasted a few years. The cost to repair it was more than $200. They opted to scrap it and get a Shark, which has already lasted almost four years at half the price.
