i got in from gardiners pal, it cost me £150 with supa lite brush, hoses and a few little bits, the pole itself is 24ft and to be honest i was really concerned about having the weight all day going from 17ft, the 17ft pole just dosnt cut it for my work and i dont think opening out the pole fully on a lot of windows does it any good, i would definately go for the 24ft with the super lite pal you will reach town houses with ease and that is without over stretching the pole...
