I'm not sure what "reasonable" for kits is anymore (have you seen kits on Ebay lately???). But you can't go wrong with a Sig Kavalier or Mid Star 40. Both are under $100 and are full kits with plans and hardware.

Early RC kits has a reproduction kit of the Falcon 56 and the Senior Falcon. They are more pricey but are nice laser cut kits with all the wood necessary and plans. No or minimal hardware though.
