Thanks for the nice email exchange, Matt.
Chahid – I am using the HVX200 in Iran and I find it works well, particularly with four 32GB cards (a bit expensive) – I would second John Burgan's advice about looking into the HPX170 – (smaller/lighter/wider lens/better picture) – unless you really want to be able to shoot standard definition material onto DV tape, in which case the HVX200A would be the right choice. But it's a much bigger camera, and if you don't need DV tape recording there's no reason to get it now.
I haven't tried the Sony cameras, but other people here say they're good.
With all of these cameras that record on solid-state cards, the biggest thing to get used to is the new workflow. At first it can be fairly daunting to have to back up all your material onto multiple hard drives or other media, but I have found the more I work this way the easier it gets. It's very much "drag-and-drop" to get the material off your P2 cards and into hard drives for editing. I'm using 500GB Lacie portable drives in the field – I have 12 of them and they're very light and seem durable – it's enough space for about 100 hours of HD material, all backed up on separate drives. These drives also run off the Firewire cable power from a Mac Powerbook, so you don't need an extra power cable, and they're small enough to put in a baggy pants pocket.
