hey guys i got this casio exilim that takes great outdoor shots for work but for some reason every shot i take of my tank comes out crappy and very blurred. i was wondering if there was a good digital camera i could score for less than 250 bucks. if anyone knows, please let me know the brand/model so i can do some research. hopefully it is something best buy has in stock because i need one real soon. thanx for the info...
