For a dorm, I like Marshall Class 5 at $399.00, can plug in headphones.  They also have ironed out kinks from 1st edition.  I thought at low volume had a nice clean tone and turn it up loud for crunch:    http://www.musiciansfriend.com/amplifiers-effects/marshall-class5-5w-1x10-tube-guitar-combo-amp/621064

Oh, so many options...
