I've heard good things about ielectrica.
I bought my B6 from a similar eBay deal from a similar company at the end of February, and it arrived with a faulty panel (slightly bent/broken in shipment or a factory lemon).
Thankfully, LG covered the panel under their warranty and the company I bought the set from refunded me $250 for my troubles. So my "Is this too good to be true?" B6 at $1400 became a slight hassle, but for a B6 at $1100. I would've never been able to get this set under any other circumstances, and the company I bought it from could not replace it, only fully refund it, which is why I opted for the LG repair and partial refund.
Just know there are risks. Read the fine print, and know that LG's Customer Service is top notch, or at least it was for me.
The B6 is an absolute show stopper, and OLED has changed my viewing habits significantly. The E6 deal looks incredible.
