I have a e500, got it a little over a year ago. I loved it.
However, now I have an e510. If you can save up for the newer model, do it. The extra 2MP might not make much difference, but the image stability is to die for!! It makes such a huge difference in low light situations.
I have shots from both cameras on my dA page, the very oldest files are taken with my old Konika point and shoot though. Only 3.2MP, and you can tell.
