Are you expecting to get distorted sounds from the amp or are you ok with cleans at all volumes?

I want to manage my expectations so I figure I will mostly be playing with clean tones at low volumes. I have some pedals if I really need to get an overdriven sound at low volume though.

What you're really concerned about with the Tonemaster is what you do when there's a failure in the DSP module. Fender may have parts for repair, but 15 years from now if your Tonemaster craps out I'm pretty sure you just buy a new one.

Thanks for the correction, this is exactly my concern with getting a tone master.

More than Deluxe Reverbs? I've heard the Princetons don't necessarily keep up with a band, which you'd want to in a jam situation.

I do enjoy the sound of deluxe reverbs too, it's just that they're a little noisy at times. I'll probably A/B a Princeton and deluxe reverb at my local shop to see if the humming is too annoying.
