Need some idea of budget really

.
Of the two you mention the AE300 is definitely better in every area than the 200, but depending on your budget you can get a lot better still for not a great deal more .. the Sanyo Z2 and Panny AE500 are both just over the 1K mark, pretty much equal in quality and both major advances over the AE300.
The usual advice is go and have a demo of machines you're interested in, though not everyone is in the happy position of having such facilities relatively close to hand.
