I use PT4 and I have been experimenting with different downloadable, custom HUDs for it.

I've been using "Justin's HUD Of Death" on there. It's amazing, actually and has some incredible pop up work done on it. There are tons of HUDs, stats, and replayers offered on that page though and also a lot of commercial ones available if you do a Google search.
