Just did the same thing
Marik, I've just gone through the camera hunt myself. I used Walmart.com to help me choose as they give pretty good info on about 400 cameras.
The Olympus Stylus 9000 was one of my short listers, but I ended up with a Canon Powershot A2000 IS.
It's less costly than the Stylus and had two of the features I wanted: the ability to use normal AA batteries and the SD memory card. I figured if I got stuck, it would be easiest to get batteries in a hurry, and that card seems to be the most popular, making it unlikely that the camera would become obsolete anytime soon.
I once had a 35mm SLR with a 200 mm lens, so the 6X optical zoom was equivalent. It's got enough variation in settings that I think I can get some good shots with enough practice.
Best of all, it was just under $200 on clearance at Walmart. That way I could hold it, test it out and talk to a human being about the features. My Walmart has experienced camera salespeople so that was a bonus.
I am still learning all about it, but I'm happy with the pictures I've taken so far. One thing I would like it to do that it doesn't is to allow optical zoom in movie mode. Maybe a small detail, but it might turn out to be crucial during the concert. Time will tell.
I hope this helps. Good luck!
