Hi Gang,
I just pulled the trigger on a Stage 1 and 2 + DICE for my 4.8is. Talked with Jason at length and he answered all of my questions. He is the product developer and made me feel very good about my purchase (so far). I should have all of the equipment by next weekend, hopefully, and will post the results!
