He runs his own server and sometimes it is down(Runs it in a spare bedroom, and when guests are over he shut's it down). So sometimes it seems like a dead link. The majority of the time it is up and running though. Very clear pictures and descriptions of what you need to do, and you should be able to tell if you can handle it. If not the Blitz65 is offering assembled kits.
