So, know of any that arent ridiculously expensive?
I could buy a used champion 600 for $100, so... yeah something obviously of better quality but not too expensive
something I can crank at night
You would be surprised how loud 5Ws can get. Cranking mine whenever my parents are home isn't really an option, but they are easy to get nice and queit, I just use my OCD or TubeScreamer when I need quiet.

You could try modding a Champ or Valve Jr.
