It's not worth it when you can get a unit that performs significantly better for about 350 bucks, new, and isn't going to die a month after you buy it, plus has a warranty besides. The fact that you are happy with the unit you bought in 2015 doesn't change the fact that spending 200 dollars on a five year old laptop when they generally only last about that long anyway before they start having problems, is just ridiculous IMO. Five year old laptops over 150 bucks is almost the same as throwing your money in the trash and lighting it on fire.
