So I know the Lenovo outlet has the 9-cell for my T43 in stock, which I will probably purchase with my next paycheck.

What I am curious about is if anyone has purchased a battery from this company:

I did a bit of googling and they seem to have good reviews, a physical location and phone number in the US and seem to be on the level.
