I'm ready to replace my aging XHA1, and have narrowed my choices to either the AC90 or VG20. I mainly do event videography (mostly weddings) but also do short films, interviews, etc. In and effort to go tapeless and keep up with current IQ, I recently purchased a HF G10 and an A77 which would play B cam to whatever I buy. I've read tons of reviews on both cams and realize they both have pros & cons. The more I read, the more undecided I am. Until I started reading about the AC90, I was sure I was to get the VG20, especially with the current $500 discount at BH. Any suggestions and/or recommendations? Thanks.
