This thread is about the new Super Duo but a few brought up the good price of the Duo III+ at ultimate hobbies.

About the cheapest you can get the Super Duo is at allerc.com with the 10% coupons they have (GOOGLE10 or YAHOO10). Works out to ~$250 shipped. To me the dual screens and the extra wattage are worth the extra $60 over the Duo III+. Only thing I dislike is the new Super Duo looks substantially larger than the original Duo line.
