RE: Cometition sailplane?
Not wishing to be a total jerk about your question, but it's so vague you may not get the answers you are looking for, even if a number of people responded. I would imagin that some won't respond because of that. May I suggest that you put down a monatery amount that "you" can afford. What you call affordable may be out of my range. Would you prefer a kit, moldie, or one like the Dragonfly Strong, a glass fuse and built up wing? Do you want a RES or full house, does that matter? You could go look at soaringusa.com and arthobbies.com. to name just two companies. That might give you some idea what's out there. Good luck.
