The shock input melonpeel gave seems very interesting. I personally haven't seen or run the setup, but seems like it would definitely be worth trying out. I agree the UE stuff is expensive. As far as quality goes though you wont find anything better. The ue diffs truly are bulletproof. You can get sets off Ebay for around 150. Seems high, but if you start going through diffs it will start to add up. I do agree you need to have balance between the aluminum stuff and the plastic. Do yourself a big favor and get a good set of hinge pins. Its not fun pulling bent pins out of the bulks, especially when they're aluminum.
