While not the best way to begin - you don’t learn as much - you might be handicapping yourself when it comes to repair time in the pits - yes there are Kits that may speed the building process along.

I will leave it up to you, the reader, to decide on the merits and drawbacks of each of the offerings listed below. New products are coming out all the time - if this is the way you want to go - research - buy - build - and do yourself a favor - CUSTOMIZE!
