My friend purchased a set and it's pretty good for the money, although I could hear problems. But those problems are based on comparisons to my Monitor Audio Silver setup, which is in another price bracket. They are better than a Cambridge Soundworks cube set, and I would venture a guess that they are better than other HTiB setups. The subwoofer definitely is.
There is also the SVSound speaker set, which was recently reviewed here. Secrets has a review of the Hsu VT-12 setup. Another option to consider are the Ascend Acoustic speaker sets.
