My vacuum cleaner, which I bought a little over a year ago stopped working (the motor still works, but there is no suction). I am torn between buying a cheap replacement and going for an expensive model that might not break in a year. The problem is that this vacuum was a replacement for a nice, expensive one which also broke in about 3 years of use. I could try to get this one fixed, but that would probably cost at a minimum $50 and I can get a new crappy one for $70 or so. I don't know what to do. Any advice?
