Well, there's always eBay. I had good success with replacing my friend's Presario screen using eBay. I'm pretty sure his was a 1270.
But my #1 suggestion is try
www.laptop-resource.com. The guy's name is Hank, and he's got a pretty good selection of new and used Laptop LCDs, and they're reasonably priced as well. I got a new replacement there for an HP laptop - HP wanted $550 for a refurbished screen, plus trade in the old one. I got a new one here for just $200.
