Adorama has their "Flashpoint" house brand version for $18.95 with charger and $9.95 for single bats. The reviews are typical, a 50/50 love-hate. Just slightly less power than OEM.

Don't waste your money on eBay for those 'OEM' look alike LP-E6. I bought three of those supposed OEM LP-E6 and all had very poor fit. Actually, they won't come out upon releasing the latch.
My new 7D and the battery that came with it has the same problem. Have to hit it pretty good with the palm of my hand to get the battery out. So I'm not sure you can blame it all on the batteries. I'm thinking of getting a grip just to avoid this problem.
I ended up getting a flashpoint battery and charger from Adorama as well-I needed a spare LP-E6 for a trip to SF-the originals were over 100.00 at the time, and no one had them in stock
It gets through about six 4 gig cards (800 some shots) before it just suddenly dies, so its ok-just no warning from lcd screen
