The Festool vac is unimpressive, for the cost.
Honestly, I'd try to dissuade you from the Fein, too.
For $99, you can get one of these:

170CFM, and nearly as quiet as the Festool or Fein (you can have a conversation while it's running).
For another $30, you can add a CleanStream Pro HEPA filter, and for another $20, an auto-start tool trigger. Probably another $30 for a 1.25" diameter hose. For under $200, you've got a HEPA shop vac that moves a ton of air, and you don't need a separate "dust extractor" for the power tools.
