If you want just the 1X12 cab. You got very little choice here. I think it's even difficult to find a dealer who stocks any at all. (eg. SweeLee- peavey 112, meant for bandit)
One other alternative, get an old or spoilt combo amp, and discard the amp module, you got a cab already. (also not very easy to find too) I think ron of blueprintstudio is clearing his crate GXL80 amp on yahoo auctions.
