Perfect vacuums and PN
I have both the Perfect C101 and C103. The C101 is a metal canister, looks very similar to the metal luxes. It uses a two stage Ametek motor and I think this motor was also used in some central vacuums which is why it is so powerful. I'm not sure if that one is made anymore, it may have been discontinued. The C103 is a plastic model and uses a one stage motor. Interestingly, both models take the hose for the metal luxes. The Perfect HEPA bags are very good, I use them in my Perfect and Lux models.
The electric connection on these hoses is a standard two pin so if you're not happy with the Lux PN, you could pair it up with a PN from Sebo, Lindhaus or Wessel-Werk. I have tried this and it works great. I know some people prefer to only use the attachments that are made for a machine, I tend to take the approach of using whatever works the best, if that means combining different machines and attachments, I'm fine with that. I think that's known as a frankenvac.
