Ofcourse, I am confused and need advise to buy
If you like photography and see yourself getting more involved with it over the next couple of years and maybe forever, I would say pass on the P&S altogether.
You will get a lot more satisfaction and superior quality results from a DSLR. Even if you buy a cheap camera now, next year you will long for a DSLR, so just bite the bullet and do it now.
If your price challenged, get a good used A200 and you will be leapfrogged into a different world of photography right away.
