Here is a random thread I found on this site. Probably related to what you're looking for. Just a link to a link to an unbiased objective and subjective review, with discharge curves.
But in my experience Harold, you're wasting your time. But good luck trying to dish out some education!
edit: opps, didn't PM ya, saw that too late. The original thread didn't get closed so this one is probably good too. (I didn't do any flaming in my post, so don't blame me).
