At Dell.ca you should be able to get a Inspiron 15" Laptop for a little over 500. I understand it's more than you want to pay. I just thought I'd put it out there.

If that is more than you want to pay for you might want to look at these.

I'm not quite sure if 11 inches classifies as a netbook, but if i recall correctly it's not that small. My sister has a 12 inch screen I do believe, and it is big enough to watch movies on. I'm sure you looked at them at Best Buy so you'd know if 11 is too small for your purposes.
I'm pretty sure you can custom colour those laptops too.
If that screen is too small then I would look for used 15 inch screens. I wouldn't buy a 2 year old laptop because computers seem to crap out within 3-4 years. And I wouldn't know where to get used laptops. I'd check kijiji. Should be able to find some around 300 with a good screen. Other than that I have no idea.
I don't know how helpful this was.
Good Luck.
