Sustainer/turbo gliders

Was hoping to get comments regarding a glider with a sustainer engine. Would you buy another one, are you happy with the sustainer, do you wish you had gotten a motor glider, a pure glider, how do you fly differently, do you actually get more soaring in or less because of the extra weight......

do you use headsets for hearing protection with engine running... engine can achieve a positive rate of climb to what density altitude....? Am considering purchasing a glider with a sustainer and am looking for all information I can get. i am a Western USA pilot, but have flown in many parts of the country.
