Is this machine any good?I am currently using a Ninja 400psi but the running costs are just too high - for example a new pump head (only the head) - £222.50 + VAT. I have spent over £1000 in the last 6 months on this machine.I am looking at the Prochem machine because I have a local supplier who can carry out repairs and a much more reasonable rate, not to mention the parts being considerably less
