Anyone else looking for an extra?

I've gone to the usual Ebay and found the 900mah unit for the Verizon version and don't want to lower capacity. I think voltage, which counts, is the same, etc. Has anyone else picked up an extra? What size? There is a 2000mah, non-sprint certified, litium battery out there that comes with a new back for the phone (its thick). I'm pretty happy with 1,340mah, but can't find one on a USA site, or for less than ~$100 internationally (no way).

Are we stuck going 900 vs 2000mah (seen 1800, too)?

I'm not ready to post a review of my new phone, but can attest to getting 2 full days on ~1 hour talk time, with EVDO and Wi-Fi off. Battery takes almost 3 hours to charge when looking at the battery indicator within Start/Settings/System(lower tab)/Power. I think I'd get more if my Sprint signal weren't one bar at home and, obviously, if I turned the thing off at night.
