I flew into Les Eplatures (LSGC) from France a couple of weeks back and received the warmest welcome ever, thoroughly worth the trip if you fancy a look at the Jura. Good entry point to CH as they will sort out customs blah blah for you without any hassle (via Colmar maybe, also a good customs choice as nobody ever there). Interesting approach too...

Another place well worth a visit, quite near Zurich, is Birrfeld:
Fliegerschule Birrfeld: Flugplatz Birrfeld
Watch out for the rules on entry and exit if flying in from France as CH are in Schengen but not the EU, and have a special mutual "(dis)agreement" with France which means you must use a customs airport on exit from France and entry to Switzerland. Other Schengen countries play nicely with CH I believe.
If you end up anywhere near Basel, give me a shout.
Enjoy..
