Roger builds them on an as required basis. Turn around is about 6 weeks. I did consider the American Beauty units, but when you factor in shipping to Aus and 240 voltage requirements, this RSU comes out on top.....for me anyway!
I did some soldering on scrap brass last night and was extremely impressed on how easy it is to use. The big plus is that you can form multiple joints in a very small area, this is nearly impossible with a normal iron.
