I have used the Nikon Coolpix 8700, Fuji FinePix 9600 Sony H5 and Sony R1 before. They are all very good cams which can take hotshoe flash. If you don't mind a 2nd hand one, these are the ones you can add to your consideration list.
If you want something smaller, the Sony V3 is pretty solid too. Otherwise, like what bro navlem mentioned, wait for the Sony HX1
