This is the Sanyo Xacti (VPC-GH4) with HD quality recording, and it takes SD card memory up to 64GB (I think)...well I used 32GB and it worked fine. It was stolen a few months ago and I bought a replacement (used) since I loved it so much. I had to settle for a slightly different model (VPC-GH2) since I couldn't find the same model for a reasonable price. The used one has some glitches, like flipping the video in the screen when recording (although the recorded video remains upright) and it likes to suck the battery life. So, I am looking for a replacement again. I do not want to buy anything heavy or bulky, and I must have SD card capability (I love that). Anybody have any luck with a video camcorder they really love? I have several ideas in mind, but not too certain. The GoPro looks good, but I do not know if it is suitable for my purposes.
