And good thing about 2012 and early models is that you can upgrade parts. Maybe find a 4GB model for cheaper and upgrade it.
Lastly it gives me about 4 hours of battery life, doing school work (presentations, documents). If I use PhotoShop, it lasts 2 hours and I call it a day.
I recently got a second hand mid 2012 Macbook Pro for roughly 150 USD. I live in a third world country and I would call that a good deal. It has 8GB ram, 250GB SSD. 3rd gen Intel CPU but gets the job done.
I use PhotoShop very much, besides school work. You can maybe find something similar on eBay.
