I'll do like I do with everyone. Toshiba Toshiba Toshiba. They have good prices and good specs. I got a Core i7 2.2ghz w/ 8 GB of RAM for $750 USD which is pretty darn good, imo. Only has integrated graphics though, so that could be improved.
Definitely check out Newegg. http://www.newegg.ca
This is a darn good laptop for the price. It has dedicated graphics as well. It's a bit bigger than 15 inches, but not much. It's 15.6".
Here's another option.
VM me if you need any further assistance!
