If you haven't already, do take a look through the Amazon bestsellers in compact cameras
. Browsing through there and seeing the differences in cameras should give you an overall gist in what sort of camera body your looking for, but make sure you have a thorough read through the specifications to see what each camera has, and how they compare. I usually do a ton of research on what camera to get.
I've been looking into getting myself a new compact lately, as my current one has really had its day. I don't really use it much, as I use my SLR most of the time, and it only really ever comes out on theme park trips so I've been nosing around for a decent one with the capabilities I need. Theres a camera I've had my eye on for some time now which is the Canon PowerShot SX150
By the look of it it seems to tick the boxes, with 720p video, full manual mode, a good zoom range and good resolution. I'll probably be buying this seeing how my gap year plans turn out to go theme park interrailing. Of course I don't actually have it so I can't give you my opinion, but it's just what I'm looking at currently. It seems well suited to theme park photography and I believe its what the guy over at roller coaster philosophy uses.
Hope that this helps in someway.
