Hello, I would greatly appreciate it if you guys could give me some advice. My MBP is finally dying, and I need a replacement soon. Unfortunately, it came at a time where I am not in such a great financial position. I am going to start a new business venture, and my computer will be something I use several hours a day for work. I will mostly be using it for Adobe CS6 and web page editing, but I might be doing a little bit of SolidWorks. I was looking in the range of $950-$1550 (used on eBay), depending on the best bang for the buck. On the low range of $950-$1050, I can find a used, low end, mid-2014 13" MBP (8gb RAM, 128 SSD). On the high range of $1500-$1600, I can find a used, low end, mid-2014 15" MBP (16gb RAM, 256 SSD). I was looking into these because they are the latest models and have retina screens, but I noticed I can find some bargains on the 2011-2013 models. Would you guys say that I should look into the older retina models for a better bargain? If I could save a hundred bucks on getting a 2012 model, would this be a better choice for the long run? Would you guys recommend a certain model that is the most cost efficient? Thanks so much for reading my post!
