You want an easy first time build and free plans that you don't have to worry about where to get them?
http://stevesarlls.homestead.com/spadworld/spadet.htm for the "SPADET LC-40" It is a nearly direct copy of the LT-40 but done in Coroplast. Very inexpensive to build. Very durable and... flies just like the Sig balsa and lite-ply model. (there is NO negative point to this airplane!)
