Personally I'd be looking for a DSLR something like the Canon D400 or the Olympus E400:

It'll cost a bit more but gives a better platform than the ones you were looking at. IIRC Olympus has interoperability between it's digital and film lenses so you should still be able to use the old lenses you have.
