Ampeg 810e cabs are pretty cheap and plentiful on the used market. May require a bit of patience and staking out CL. Plus, you absolutely have to carefully check them over, because the amount of cabs with blown speakers on the used market (knowingly or unknowingly, by the seller) is plentiful as well. I have a friend who only recently was convinced that they were loud or sounded good, because he had unknowingly never played one that didn't have at least one blown speaker in it. The one sitting in his practice space forever was blown and he never knew, he just thought 810's were quiet and farty sounding.
