Charge is not out for sale just yet. Today was supposed to be the delayed launch day but it's postponed again. It's only shortcoming is price. Slow benchmark is only due to RFS which can be fixed by rooting but real world usage feels no different than Tbolt. Can't complain on storage side too when it has 512mb ROM + 2Gb internal for apps + 32Gb micro SD for data/apps. But it crushes Tbolt on battery life, screen and camera. I hope Revolution beats it with pretty much everything except screen though. I won't touch Incredible 2. It's just slight upgrade from the original one with still mediocre camera, call quality.
Then, the Revolution could be a good stopgap for you until a dual core comes out. I'm still expecting the Bionic before September, but who knows with the delays. Costco is on and off on the phones they carry, and I know that sometimes Berizon does do exclusives with Best Buy for a limited amount of time.
