Good news young feller !
Glad to see you're planning to remain with the herd. Truthfully, I don't know which way you should go, rebuilding or used would be the most economical solution & leave a larger portion of your budget for monster bumpers/exo skelitons etc. But the diesel option has advantages too...especially with the price of gas on the rise. Then there is the "roll your own" option of making your own fuel from waste resturaunt oil.
Lots of different ways to go...which ever solution you choose, at least you'll still be in a VX.
