There is a set of wings and front struts on Barnstormers right now for $2k. I took a good look at them yesterday and thought they were a good value. The spars appear good and there are two 5.5 gallon tanks with the wings. I think a couple of ribs will need to be replaced. Depending on your taste, you might replace a few more just because they have quite a few extra screw holes.
There are also front struts that go with the wings. I didn't pay much attention to them, so can't comment.
If you're in the Atlanta area and need a set of wings, this would be a good deal. And I'd gladly buy the right 5.5 gallon tank from you to reduce your cost a little farther.
And, no, I have no connection with the owner.
