So I've decided on upgrading to an Orange Micro Dark. I don't really care what anyone else thinks about the amp. I've been very impressed by what I've seen of it. But I can't really afford an Orange PPC112 right now. What would be a good budget alternative for a 1x12 cab. I don't really need anything bigger than that.

I don't know if White Box is still doing things, but that 2x12 was much better than Avatar in my personal experience. There was a user on youtube who said they were as good as any cab he's used, and said it actually sounded better than his Port City.

You can find many cabs second hand for a good price.
