I think the best plan is to figure out what you want set up a "buy" list with the venders you want to work with and then stay the heck off the PT boards untill you are done

I can't tell you how much extra money I have spent because i got cool ideas or a "deal" on some neat parts that I really did not need to reach my original goals. My car is a not the car that I originaly intended to build. Blast you PT guys and your super cool stuff
