Is a used 15 inch Macbook Pro Early 2011 model (with upgrades) worth $400

Stumbled upon a deal for a used 15 inch Macbook Pro Early 2011 model for $400. It's got an 2.0 GHz Intel Core i7, Samsung 128GB SSD + 650GB mechanical hard drive, and 8GB of RAM (upgraded from 4GB). Is this a good deal? Will this machine be able to handle programming (including iOS development with Xcode) and schoolwork smoothly?
