In the sub 20k bracket preferably even less is there a particular make/model that won't bite you? Wouldn't have a big workload by any means but reliability would be good. Something like a jcb 526s. Clearly from ad's I've seen I'm looking 20 is yr old machines.
Or is it totally pot luck
530/70 can be had for under Ā£20k and is reliable and relatively easy to fix. I found a couple of them and very neatly bought but in the end we got a 541/70 for Ā£25k and 7000 hours.
