If you are comfortable with heavily used cameras, the first generation Olympus E-M5 body only is available in “Used – Very Good” condition starting at $244 [WAS $225; updated 7/3/17] plus shipping at Adorama. Their “Used – Very Good” condition is described in general as:
Appears well used and may include dings, scrapes/scratches, heavy brassing on body or LCD, but is in fully functional condition.
Make sure you also check further down the listing for potentially additional information, and also check under “What’s In the Box” to see what’s included in the package. Often times with used items you don’t get all the original accessories and packaging and such. Adorama offers a 90-day warranty of their own on the used gear they sell.
