without a doubt - petrol or diesel.

Kiddies toy,.. avoid.

15 litres per minute, 13HP, 3000 PSI MINIMUM!
The flow rate is actually more important IMO than the pressure. A good turbo nozzle will make up for lower pressure, but a low flow rate is a disaster. I have 2 machines,.. one is 4000psi and 14.5 litres per min, the other is 3000psi and 17 litres per min,.... the 3000psi one does a noticeable amount more work in the same time.

I got a Lonicin engine machine off him for an absolute steal and its proven to be a real reliable workhorse. Honda is best if you have the cash, but a loncin machine will work away for a couple of years while you're getting setup properly.
