If you want a good Epiphone acoustic, I suggest you go for the Epiphone EJ-200.. Timo Kaltio used a black EJ-200 on his acoustic parts on the 'Smoke' album. While Izzy used a Gibson J-200 (the more expensive Gibson version after which the Epiphone is copied) on the 'Wave Of Heat' album. He also used a Gibson Hummingbird, of which there's also an Epiphone Hummingbird version.
I've tried out the Epihone acoustics and if I were you I'd check the EJ-200 and the Hummingbird out aswell, the EJ-200 sounded better then the Hummingbird I found so I bought that one, but both are good. Actually the EJ-200 is a Jumbo acoustic so it's got a great rich sound..
