I have found that the Fuji5000 is a superb camera, I paid about £200 for mine about 9 months ago, it gives superb quality is very easy to use, but its drawback is lagtime, saying that once you get the knack it can be coped with. Also, allways have a spare set of batteries handy, you get very little warning that the installed ones are about to quit. I still use mine all the time.
If you can splash out (£800) treat yourself to a Canon EOS10D Digital SLR, quite simply 6MEG Pixels, no lag, and a very nice piece of kit, brilliant for shooting moving aircraft. I have Canon wet cameras and all the lenses I have for those are compatible.
I also found it best to read user reports from the net, I got some great feedback when I was looking to upgrade to my Canon,
Good hunting
