My thoughts for what they are worth. I had a 70-200L non IS. I sold that and bought a 300 F4L (IS), that got damaged so claimed on insurance. Bought myself a 50D, sold old 400D and bought another 70-200F4L non IS.So my views.
IS is another money spinning gimmick to a certain degree, I would have thought the two big names could easily incorporate that function within the body.
Learn how to develope your own comfortable way of holding your camera, there is no right or wrong way, just what feels good. Besides every situation will require you to be taking shots in a different position.GlasgowGunner was right in a way about the good old days, although I think todays DSLR`s seem to be a little bit more sensitive to vibration.
Learn how to control your breathing, this really helps.
Learn how to relax, nothing worse than having that great shot opportunity and you go all tence.
Depends how much money you got to throw at the hobby, which covers everything. Do I need one flash or two? I own a 300MM should I buy a 400mm? Should I get a 2.8 or F4.
Just think about your needs and how much you will use that piece of equipment, does it warrant spending the extra couple of hundred. Think about the little extras you might want along the way, those little bits soon add up to a couple of hundred quid. Only you know the answer to that. Good luck in whatever you decide.
