Yes good idea Andrew.
But, I have to say, as with everything,
the problem is too many choices these days
I find the 12' good for all your average economy 1st floor modern houses. I wouldn't be without it. But I have an 18' for bigger stuff. Once extended, a lot heavier, even though claims of being light!
Check how high you want the little lady to work. And get that price list from ionics before you buy. Always best to get things in print. Gives your mind time to absorb. Be patient.
