So you have two options if you want to shoot at distance, a good camera with better lens's or you go with a digiscope alternative which allows you to shoot a simple point-and-shoot through an spotting scope.
Do you have a nice spotting scope? If so I would lean that way, I've done it successfully with point and shoots for some great pictures (my spotter isnt all that great either). If you want to go the camera with bigger lenses then it all depends on budget. These are getting great reviews:

I emailed them about it as a few cameras had bad CCD's. They emailed back and said "Oh really? We want to see your unit" and sent free shipping. I sent it figuring it was toast but a week later it came back fully repaired with a apology for my troubles).
Point-and-shoots, look for OPTICAL zoom and high megapixels. Third you want fast image taking (some high megapixel camera have slower ISO speeds so some pictures get blurry... very important to have a fast ISO when taking zoomed pictures).
Love to hear what you end up with. My current camera is getting some age to it.
