I was wondering if anyone has any power zoom setups they are impressed with?  I've considered a digiscope with IPhone but the quality seems to be lacking.  I would mostly be using it for filming game from a distance.  I have a small camcorder that is great for scouting but would like something similar to zoom in for taking pics.  I'd like to keep it under $400....not sure if that is possible but there are several Canons and Nikons that look pretty good.
