I think you should build because you want to build, not because you want a spanky airplane. Lots of these kits never get finished, possibly because the builders wanted a spanky airplane and didn't really want to build. An RV10 is quite a bit of building. Figure it out. If you want to build, build. If you want a spanky experimental, go buy one. Odds are you won't pay any more into the experimental than the builder did.
