Exactly!! If I saw a 913 at a thrift store for $20, I would have already disappeared with it; when you snooze, 99.9% of the time you DO lose--and I've learned the hard way!
Jeff, that model 90 looks fantastic, as do your other commercial machines!! Does the Hoover Historical Center have a working Model O on display along with the others?
Interesting information about the P/N-equipped Quik-Broom as well; you'd think Hoover would have priced it a little less than their entry-level Convertible in order to compete effectively with the others. Needless to say I would LOVE to find one of those!! It would be a perfect match with myself, considering how I change bags quite frequently...;-)
