The Libelle makes a fine first glass ship in my opinion. The one Hank is talking about (JR) was owned near me years ago and was my first glass flying.. In my opinion the handling differences between glass and everything else is over played.
You'll be fine! I'd stick with the 201 for a first glider for a low time pilot. You dont need the flaps of the 301 just yet. It's been a while but if I recall correctly the 301s had a balsa core and the 201 foam? Not a big deal, but something to consider during a pre-buy inspection.
