Well 16GB of Ram from OWC is $195. Pretty pricy. Do you know if I can get it cheaper somewhere else?
EDIT: Would this be the right one? Seems to be according to MacTracker. http://www.canadacomputers.com/product_info.php?cPath=24_326_327_609&item_id=044914
I paid less than $90 in February of 2013 for 1600 MHz RAM from Newegg. I am not sure how that works since you're in Canada, but you can put regular 1600 MHz DDR3 in there just fine!
