Pressure washer recommendations

[BenjiSayers]

Why are you after a new gun?

I wanted one of the smaller ones so it was easier to move around.

Need a new pressure washer hose and its old so think might be worth replacing my old Black and Decker PW1700.

Anything i should look at beyond a Karcher K3 for £98 (power control or classic as options)
K3 horizontal probably a bit compromised performance, or ok just no wheels? and only £70

Thanks
