Thanks for the input, some good things to take note of there. I could probably make use of nearly all of the attachments, as mentioned decking is first point of call, then got a load of flag stones to clean, house windows, both cars etc, only things I wouldn't possibly use would be the brushes....
I do like the fact that is has a specific car nozzle for the unit, other than the one with a little ball bearing in it, have heard that they can be too harsh on vehicle paintwork.... (surely that's a case of move the lance a bit further away to compensate though...?)
I'm leaning more towards Nilfisk as the pumps are better, and this has an induction pump rather than the universal motors most come with.
This will be my first one pressure washer though, so want to get it right first time, rather than spend cheaper and end up replacing it in a couple of years time.
