Sold through the Polargraph Shop.
Buy a PolargraphSD machine or a vitamins pack and it’ll be ready in a week or so if I’ve got parts to hand, about three-to-four weeks if I need to wait on some of the slow things. If you’re in a hurry and want to check what’s in, just drop me an email or twitter me or something. Can’t believe I just said that.
What you need:
The instructable probably gives the best overview of what building and set up is like. Read through it and see if you think you’d be ok with doing it all, because although the kits do contain all the things you need, it isn’t plug-and-play and you will need to do some assembly, and spend some time getting it right. A couple of evenings.
The setting up your PolargraphSD page is the best place to see what comes in the kit, and how to set it up.
