Nilfisk. I've got a C110 around 5/6 years now. Bought it on offer in Argos for less than €100! Never missed a beat for 2 cars, an extension self build and general house fascia maintainence in that time. C120/130 are a little dearer but are no where near €300!

Bare in mind, if you have a snow foam lance, you may need a different adaptor depending on your choice of replacement.
