Kelly,

With the trailer, shop, and field issues out of the way, I think your only choice is the 40%, at least in my mind. It certainly would be a lot cheaper than building, setting up, and flying a 35% for a while, then selling it. The best most people get is a price less than the sum of the parts when selling. You would be out a lot of time with building and setup to boot.

Do post a follow up once your 40%er is done
