As I planned to have a video camera before my first daughter born, I tried hard to find a good one - in High Definition format. Last time when I was in Shanghai on March 08, I almost purchased Sanyo Xacti HD1000 for 4100 RMB, luckily saved by self-control device (read: money). Now, 6 months later, after browsing and find people review of HD video cam, I ended up in 2 options: Sanyo Xacti HD1000 / HD1010 or Canon HF100. Both have different plus points.
Xacti product brand is always come into a pistol-gun size, ergonomic and fit into a palm, easy to carry to anywhere without needing big bag. Even it can be slipped into jeans pocket. It is lightweight because uses flash memory instead of using mini DV or Harddisk as storage.
Canon HF100 is the latest lineup from Canon, comes in HD output format, also uses flash memory as storage (HF10 model comes with internal memory). Plus point is it uses OIS (Optical Image Stabilizer) to minimalize hand shake.
