Save your first "kit" for something else. The Super Sportster is a terrific plane, but by the time you buy the kit and the covering, you'll end up saving about $00.25 per hour for you labor.

There are any number of good kits out there, but I'd say buy the ARF if you want a Sportster, buy the P40 if you want to build a kit, or buy both and fly the Sportster while you build the kit.
