Those Fuji slr-alikes are really great but probably well over budget, this is a camera that has had good reviews and lots of features: http://www.pixmania.com/ie/uk/382392/art/canon/powershot-a710-is.html?itag=6051 and comes in just a little over budget.
If you want to stay with Fuji and within budget, this is a great camera for low-light situations and may take the same memory cards as your old one: http://s35310688.einsundeinsshop.de/sess/utn;jsessionid=15466526eeec09e/shopdata/index.shopscript
