Suggestions? Boy, are there. The interchangeable lens / Micro Four Thirds market has exploded this year, making up nearly all of the news that flowed from Photokina in September. Panasonic's GF2 has seen glowing reviews, as has Sony's NEX line. So, readers, what do you recommend? Speak out in comments below."I really want a new camera, but not a point and shoot -- more like a DSLR or a Micro Four Thirds. My budget is $300 but I can go up to $400 if there's sufficient reason. I really want to get a new camera before Christmas. Any suggestions?"
