I am in the market for a budget used iMac that'll get video/audio editing done (especially After Effects). I've come to two affordable options that I will present here for your valued advice. 1. Late 2013 21.5in - 16gb RAM from macsales (OWC) in Excellent condition, 90 day warranty $629 - here 2. Late 2013 21.5in - 16gb RAM from macofalltrades in Very Good condition, 1 yr warranty $658 - here The main difference here is the company selling and the warranty length. I am looking for something that will last, while being aware it is a 6 yr old computer. Do you have any advice on these two websites and the idea of shorter/longer warranties given the pros and cons of each? thank you!
