i have the pv-gs300, and ur wrong, there r lots of differences between the 180 and 300. the main one is the 180 uses electronic image stabilization which reduces image quality, while the 300 has optical image stabilization which doesnt at all, so wen ur doing follow cams the 300 will keep its great picture quality while the 180 will look degraded qualitywise. also, the 300 has a leica lens, flash, no remote, and no widescreen mode. the best thing about the 300 is the OIS, its worth it just for that
