Thanks A6A6.
You're right that 200-400 did cost a pretty penny but it's a hobby that I enjoy a great deal. My main hobbies are hunting and fishing and photography so that's where all my savings usually go to...lol.
Glad you liked my Pbase site. Probably some good advice I can give you is when using your tele lens with out a tripod or monopod, try and get as fast a shutter speed as you can, that will help greatly with the blurr. A good rule of thumb is to try and have at least a shutter speed of 1/focal length used. So if your shooting at 300 mm you'd want at least 1/300 for a SS. Obviously that's not quite possible at low light at dawn and dusk, but just try and keep it the higher the better.
There's so many other factors too - I just don't have time to write it out right now.. A real great place for learning about photography is at www.dpreview.com . They have a whole learning center that covers everything you can think of. When I started out into photography 3 years ago, I didn't know a thing about it and that's where I learned pretty much everything. Good luck with that camera and post up some pics when you get a chance
Take care
