If you want to “future-proof” yourself consider the Panasonic HVX-200. It shoots DV, DVCPRO50 and 720 and 1080 DVCPROHD. It covers the gamut of what you need now and might need in the future. Editing the high def material is just as easy to do with FCS as if you were editing standard def. You can shoot SD in both 4:3 and 16:9. It is a truly wonderful camera that is incredible versatile.
