If you are looking for an affordable way to get into the world of Micro Four Thirds, the price of the refurbished Olympus E-PM1 with the 14-42mm II lens has now dropped to $250 with free shipping at Cameta Camera. Two weeks ago this was priced at $280. The black and brown body colors are at this price. The purple, silver and pink go for more.
These are "refurbished USA" but with a 1-year warranty offered by Cameta Camera (not Olympus).
If you don't need the 14-42mm II lens, they also have the refurbished factory-demo black body only for $190 with free shipping.
Alternately, Cameta has a variety of specials on E-PL1 and E-PL2 kits, starting at $120 with free shipping for a refurbished factory demo E-PL1 black body. A total of 67 (!) kits are shown at the aforelinked page! As usual, be sure to check the individual product details - some are refurbished-factory demo, some are "outfit boxes", some are new in original configuration.
