How much can I sell my Xbox 360, Surface Tablet, and Gateway Laptop for?

[http_dayton]

I have a Xbox 360 for sale with 250 GB of storage and I have 1 Wireless Controller that has a detachable keyboard to go with it and also 14 good games. Everything is still in great condition.
I also have a Surface Tablet I would like to sell, and a good Gateway Laptop.

(Everything is in great condition still!)

For a reasonable estimate, people are going to need to know the model# of the Surface and the Gateway; probably the xbox too since there were a few different ones of those.
