I just found out I have the ability to get an Extra from Pro Craft Models, which is the old Ohio RC kit. 73" span which is the exact size I am looking for. I did some searching here and people seem to have good things to say about these kits. I asked them about the difficulty of their kits and they assured be that as long as I lay everything out and follow the directions, it is easier than a Sig Kadet. Any thoughts on these kits?
