Budget vacuum tube preamp?

I got so many great responses on my last thread regarding when to go vacuum vs solid I figured I would post my follow up in a separate thread.

It seems the way to go for the amount of maintenance I am willing to do is a vacuum preamp with solid amps. I would like to have the HT bypass so I can use my HT receiver for multi ch. movie listening.

With that said, I don't want to spend a fortune but I want to hear the benefit of my purchase. Where to look for a entry level vacuum preamp and how much should I be prepared to spend?

Thx
