Same here... I'm leaning towards the SD3 but as the only real differences are the full 1920 horizontal resolution and external battery input jack, the SD1 seems to be a more sensible choice. On another forum, they were rationalizing that the SD1 may actually show fewer AVCHD compression artifacts since the same 13 Mbps bandwidth is encoding fewer pixels. Seems plausible, but on the other hand, those pixels cover the same image complexity. Sample clips are online for both models, but I don't have an easy way to play them at full 1080i resolution yet, so the quality looks about the same to me. One thing's for sure... both camcorders will only get cheaper, so if you can keep waiting, I'd do that. The CC coupon is good until the end of 2007. Me- I've got a baby daughter who isn't getting any younger, so I want to settle on one this week and get shooting.
