I must admit the new Olympus E-420 with the 25mm pancake lens could make an attractive alternative to this (assuming the Foveon sensor isn't the main justification for buying). I've an E-400 which is similar in size. With the new pancake lens it'll be an extremely small and lightweight package - but with the option of changing lenses if you want that. You also get the very nice 10mp sensor as found in the E-3. Price is comparable too it seems.
