[RE-wrenches] Sharp modules

[Drake]

What do you think of the quality of the new Sharp modules?  The 240 
F2 has a good PTC rating, but a power tolerance range of 15% (+10% 
-5%).  With the frame and construction issues, I wonder if the 
quality of Sharp modules is slipping.

Has Sharp cut quality to keep competitive?
