Its annoying that im down South , i got so much in the shed and garden that sits there doing nowt, maybe ebay is the way for me, off the top of my head i have 100 psi pump,175 litre tank ,250 litre tank , 25 foot brodex hydra , 9 foot brodex hydra , brodex brush , gardiner 18 , vikan brushes , superlite stiff , radius stiff , varistream analogue , 45 psi pump , ROsystem ,
I know this dont help you but in your shoes , i would get red hat back pack , maybe a gardiner cos its not much more , Ro can be had for 80 to 100 i think , your prob is the pole cost as you need to go 3 story , by this i take it you mean G,1,2 ?
The only thing i could help you with is the pole , assuming a 25 foot will be long enough , not sure now , i currently use a clx 27 for this , like i say the pole is going to put you over budget , i could let you be in possesion of this pole cheaper than a retailer could by far , but it will only have the vikan or brodex on the end , i will even hose it up for you !
It wont be as light as a clx but it will let you do the work in hand , in fact im gonna go get the mighty brodex and clx and compare the weights , let me know if you want a bargain .
