Best Bass Amp Head for under $300?

EDIT: I actually picked up a Peavey Mark VI head today! We’ll see how it sounds. I’ll report back

Hey all, I’m looking for a fairly cheap, used Bass Amp head.

$250-$300 price range.

I’ll be using a RAT and a Sansamp on my board, so ideally something that will play well with distortion and be loud enough to hear in a band setting.

I’m open to other suggestions, But here are a few that have caught my eye:

Darkglass Alpha Omega 200

Peavey Mark III, VI, or VIII, Peavey Centurion, Peavey Century 200H,

Ampeg SVT-450H, Ampeg SVT-350, Ampeg B2-RE, Ampeg PF-350

Any advice would be appreciated Thanks!
