I recently picked a mid 2013 1.7GHz i7 / 8GB / 256GB SSD MBA for $300. Only issue this laptop has is a very small light surface scratch on the display back. After charging the battery I found it had 400 cycles on it. Currently the battery health reads at 87%. I was able to run the laptop all day long before putting it back on the charger. Not bad for a $300 item
Compared to my 15 inch and 13 inch MBPs I can't get over just how light my new to me MBA is. Amazing machine!
