I'm actually somewhat the same way in that I'm really more into scale building than fun-fly type planes. I have a couple, but they aren't what I enjoy building. I'd take a look at the Top-Flite Cessna or the Piper Arrow II. These are civilian plane kits and for me are a bit easier to build than some of the warbirds. They also allow you to get as detailed or (not) as you want.

If you don't have any building experience, another thing I would suggest is getting some videos on building techniques. I specifically like the Dave Platt videos as they really show some neat tricks and ways you can save a ton of time and money. If you aren't sure which ones you need, just give him a call and he'll point you in the right direction.

Good luck.
