Sorry for the delay in responding, but thank you all for your helpful advice. i will have to make my mind up as to what I intend to use it for and how often I am likely to use it. My current preference seems to be for an Abac 3HP Direct Driven with either a 25 or 50 litre tank. I had thought that I could use it for occassional spraying of small items in the future and these both appear to be up to the job, then I read that small airless sprayers could achieve the same results. Ranger, thanks also for the catalogue - I now know where to get Kohler rings etc.
