Where can I find a NES and SNES (w/ games preferably) for a decent price?

Is anyone out there selling these classic systems or know where I can find these beauties? (preferably w/ games) I want to get these for my father as a late Father's Day gift!

note I know I can search Ebay and Craigslist, but I'm new to Reddit and figured I could learn a thing or two! :)
