not sure if im wrong or not but isnt most of the kit available separately and cheaper ?things such as the pass over uv light and the spray treatment and a kirby short handle ?.i bought a lovely set up off a bloke about 4 years ago, flight cases, goggles,test sheets etc and a little medical bag with untold wonders in it but most of it was just to prove what filthy bleeders we all are, which is probably why its usually a kirby short handled vac with the demo chamber that you can put filter paper in to show how much crap it lifts. im still not convinced there is a big uptake for it over here, just be careful when you do your first demo and take the filter out, if your goggles arent snug and you get flakes in your eyes its a weekend of conjunctivitis
