searching for news of Sunny Boy [RE-wrenches]

[Jeffrey Wolfe, Global Resources]

The BP2150's look like fine panels. Good luck getting them, get in line, 
and be prepared to WAIT. My order for 72 panels from July MAY be fulfilled 
in late September / early October, maybe not. Lesser quantities, I think 
you can forget it, unless someone has them in stock. (tell me who!)
