Thanks for the recommendation, but I am not right for a DSLR.
I had a Canon SLR (before Digital) and did not use it (had 2 nice lenses too.
Would those lenses fit into the DSLR's ?
Yes, provided they are EF lenses. These were introduced with the original EOS film cameras. Prior to that were the FD mount lenses and they won't fit.
I had a very brief look at your possible cameras before my last post and thought that if you were considering super-zooms then maybe a DSLR wouldn't be too big or heavy. Already having a couple of EF lenses, the EOS 350D might have been a serious contender at your budget but if you don't want a DSLR then I believe you have to accept that you are going to suffer from some picture noise in dim lighting.
I will pass up the offer to recommend a camera from your list in favour of those who know the cameras concerned. By the way, not my place to say it but "welcome to the Camera Labs forums".
