I bought this recently, from the very place
It doesn't do any of that five shots per second malarky, not that you need that taking pics of stones;-)
It does give you excellent picture quality, especially good with natural scenes (has a special setting) and you get nine minutes or so of film should you want it, and best of all the batteries (do get rechargeables!) allow about 200 pics in a go. I suppose you'll know all the rigmarole of having spares etc.
Nice big screen too.
