Anyone here ever tried the Olympus E-420?

I'm planning to buy an entry level camera this December and I've been looking at a lot of cameras and reviews. The E-420 was one of my picks cause asides from the cheap price of its kit, there are stores here who sell accessories for Olympus DSLR. The lens are also cheaper compared to Nikon and Canon lenses, plus for an entry level camera it has Live view which is not found on most entry level cameras. The only thing that is holding me back is the quality of the shots. Among the three cameras that I'm trying to decide, the E-420 doesn't have very sharp images in high ISO. The raw and jpeg have little difference in terms of quality. But asides from that, I really like everything else. If there are any Olympus E-420 users out there could you give me some ideas or experiences with your camera. Would you recommend it over the Pentax KM or Sony a200? Is the image quality really a big issue as mentioned in a lot of reviews?
