Hi TomI agree with Dave in that I prefer the S-1S to the S-1T as well, but if you want to fly unlimited within a short time you probably should consider the T. As far as experimental vs. certified, I much prefer an experimental certified airplane. For a single holer, there aren't any negatives and it gives you a bit more freedom. You have to look closely at the maintenance history of any airplane you buy, and of course if you're buying an experimental airplane do some research on the builder. An experimental built airplane can be better than a factory built airplane if built right.
