If you don't mind having a largish camera I'd stretch my budget a little & go for one of these...(I have the old 5600)

& one of these...(not that fast but is quite flexible)

& a couple of sets of these...(I think they're about the highest capacity rechargable AAs I've found)

Don't be put off rechargable AAs, this camera takes 4 of them & they last for AGES if propperly charged.
