Hi Robbie
Just mention preowned is great if you get a good one , but Damien and Ben do a machine on this spec for
1400-1500 or so .
You will probably pay 5-600 for a clean used one , then pick up maybe 100,s miles away so a day off and 100 in diesel . Then service and and perhaps new lance and pressure hose and you will only slightly better off.
Take the 600 budget , stick the difference on a credit card if you haven't got the cash , and knock of a couple of drives. And you will be sorted. You will be set up for years under warranty
IMO it's false economy, let alone the hassle factor if it goes down on a big job.
Cheers
John
