With the increase in 'Digital Image Competitions' in photographic clubs, where images are presented in 1024x768 pixel format, there seems to be little need now for more than 10-12 Mp sensors. I can print to A3 at 240 dpi and get excellent results and digital images are also superb. The GX-10 or K10D will fulfill that requirement well.

Better to spend your money on good glass, or a solid tripod/monopod.
