7800 is on my console get list, but I tend to try and find consoles at a yard sale, ect instead of giving up the hunt and jumping to flea bay. I've got to admit though, finding anything older than a n64 out in the wild is getting tough around here.
Before the NES me and my cousins would play on the 7800 for hours.... of course I was too young to know at the time that they got them a 7800 and supplied them mostly with 2600 carts you could get for a couple of bucks post-crash.
