I really love my DG-303 Acro with no Tax. Mine was built in 1998 under the new company so it is still covered. I am a very large guy and the DG-303 has big advantages with taller pilots. I love the big ailerons although the wiglets are kind of ugly but functional. The glider is overbuilt structurally which I like as I am a recreational flyer and not a racer. The Discus, ASW-24 and DG-303 are all great with different flavors and styles that match to different pilots. Many times it just comes down to what is for sale, where it's located, and most importantly what kind of trailer does it come with. When you buy used, the luxury of choice often get subverted by availability circumstances.
