I have an original, real Altair 8800. They aren't super solidly built (lots of individual wires), and having been sold as kits, the assembly quality on them is very variable. Among the many tens of vintage computers I own, the Altair is definitely the most finicky to keep running. If you're interested in understanding what it was like to use an Altair 8800, the software available for it, etc., this is a great way to go. I've been really tempted to get one myself.
