I'm really hoping a working 8-bit computer like a C64 comes into my wife's store soon. She just took ownership of a big thrift shop and I've already replaced my NES with one and I have many old games, ducktales being the best/most valuable game. (Lots of lesser known disney games, all of it came in from the same donation) I've been saying I've been wanting an older computer on here for awhile... but I'd honestly want a working authentic one over a reproduction. Like many people have pointed out, emulated software rarely is 100% right, (even if it's 98% right... it's still not there) and there is just something about experiencing something really aged. Putting a needle down on a record player, holding an atari joystick, rewinding a cassette tape, switching between discs on an old floppy drive... there is something really neat about that in small doses.
Anyway, rambling aside, I'm really hesitant with many of these new retro remake systems. Example: The company I just left on Saturday was a vacation rental company, I took care of 51 cabins around here. One of them has the $2100 "Dream Arcade" machine, which has tons of games, a trackball, 4 joysticks. (This thingy here

I was the first person to play on it, (installed and set up the thing in the cabin) and I played numerous games, and the joysticks lagged and had genuinely bad directions, (diagonals were really rough) and the trackball really sucked. Made playing missile command and centipede something I couldn't even attempt. This machine was over 2 grand and it isn't perfect. My godfather has an original centipede arcade though, it's close to 40 years old, and it still works perfectly.
So... yeah. I guess I just am nervous about dumping 150 into something like that when I can possibly get an original for free at my wife's store or for cheap at a garage sale this summer.
