lol, i was in the same situation, well kinda, i didnt have a hks system to start with i had a standard box, first thought about going hks then read alot of bad reviews, then looked at the arc one, looks amazing i think, but its damn expensive in my opinion, when i phoned up paul at wifbits (cant remember if thats spelt right) i said what the situation was. he was great, he could of sold me 3 or 4 really expensive ones, including the arc but instead he sold me one of the cheapest and was what they recomened and i quote, "probably one of the best induction kits for the supra) am well pleased with it and the fact that it was cheaper then the others.
