I got one of the Dolica Proline el-cheap-o bundles a while ago when I was desperate for a tripod, with the intent of replacing it quickly.
So far, the ballhead on it has done better than my old Manfrotto did-- 494 I think? The legs are pretty crappy, but I'll be swapping the ballhead to some carbon legs soon.
To echo comments above, press cameras have a pretty good center of gravity. Unless you're using long and fast glass, the weight is going to be more or less centered over the ballhead. I get by with my B&J press camera on the above Dolica without issues, as long as I don't use my Ilex 215 f/4.8 on the front of it, and crank it all the way out. Ballhead locks down without much force, and it stays put while loading holders.
Not a good long term solution though... Either keep what you have and save up for a beefy Manfrotto or Arca Swiss, or sift through people's experience and get a cheap one that'll work now, while saving up for a nice one.
Also-- I have yet to find a ballhead under $100 that I would trust my ETRS fully loaded up with a long lens on it-- a lot more twisting force on a ballhead because of how off-center the weight is. With my B&J and 90mm Angulon or 135mm Optar, it's well-centered enough.
