I have some painting to do, render, barge boards and windows. I already have
an alu ladder.

I could do with a standoff, and one with a V notch because for some of the
work I will only be able to place the ladder against a corner.

This caught my eye http://laddersareus.co.uk/access.htm#laddstand
(LADDSTAND)

But I'm not so sure about having one with wheels on it - sure it'll make it
easier to put the ladder up, but will it be as stable and safe - anyone got
a ladder standoff with or without wheel care to comment?

Thanks.
