Why don't you simply rent one first to see which one you are most comfortable with? Our recommendation might not necessary suit your needs (which in this case is not even stated - making it harder to make a recommendation) and taste. For example, the epm1 is a good camera but I simply dislike the ergonomics and the physical look.
If renting is not your cup of tea, then try going down to one of the stores (i.e. TK Foto, MS Color etc) and try it out for a moment.
