Thanks for all the replies, guys.
And yes, I know about Razoola. I'll try have a buddy of mine change the battery of the B board just in case, anyway.
I am a bit anxious, however, about the seller (danlanzar1 on ebay) because he doesn't have that much feedback, plus he sounded like a moron on his e-mails (writing all in caps, very poor English though he's from the US...). So I have my fingers crossed, lol.
