Building a practice amp w/Dr. Boogie as preamp...which power amp?

[therecordingart]

I'm wanting to build a bedroom practice amp using the Dr. Boogie as the preamp, but I'm not sure which power amp to go with. There are a few @ GGG, but I'm thinking submini tube would be fun as well. Cost is a consideration...I don't want to go over $100 (I'm married with child and now my DIY has a budget).

I already have a Firefly and a bunch of pedals, but sometimes I need to sneak in a quick practice and don't want to go through the motions of setting up all of my stuff. Having a nice sounding little practice amp seems like a good idea to me.

What are your thoughts?

Have a read through and listen to the mp3 at the top post, did that a few years ago and it's a
great practice amp.

  I like my little chipamps all the time...
  One is an 18v little jobby, Fetzer 'preamp', drives effecient 6''+tweeter speaker plenty for personal use..disc/Mp3/Guitar/ anything else.
  Other is 2 x 3886 stereo amp, Piaa Preamp, very strong.
  3 main features I really like about them:
  The volume control of Si amp works more like volume control than with tube amp, wide variety of loudnesses with a quick twist. Distortion in preamp allows volume and quick eq twists to make "almost the same" sound louder or quieter.
  Quite inexpensive, especially if doing some frugal measures to keep cost low, the power supply being the main ingredient, much easier than tube.
  Turns on right now.
  ok 4: Nice to have a clean reference ''amplification'' device.
  Tubes can be just too loud for 'useful usage' [ie the reason being that loading and speaker interactions make it 'work' the way it does...which defines: "why tube"]...these types of tones "require" [overstatement?] the speaker to 'get activated' [which is already intractably "loud".
