I personally endorse AVUncapper. In fact, I'm working with JRoush to fill out the feature set, and release a "good defaults" ESP for use with it. The only downside to it right now is that it's really a modder's tool, you need to create your own ESP to activate it; that should be resolved within the month.
If you're going to set it up yourself, by the way, I strongly recommend not raising the basic advancement cap for skills over 200, to leave headroom in case another mod gives you an ability bonus. (Breaking 255 wraps you to zero...)
