[b]Sony RDR-HX510 and previous models - confused![/b] Sony are getting good reviews for the recently released RDR-HX510. I am interested in this machine but a quick surf of the internet throws up apparently similar but discontinued models such as the RDR HX-710, 900, 1000... Has anyone else looked at/bought any of these? What are the differences between these models apart from hard disk capacity? How do they perform? I like the idea of getting more hard disk capacity than 80Gb by going for one of these discontinued models but can't work out whether I might be missing out on some major features such as progressive scan. Can anyone advise? Thanks.
