The subject really says it all.

I'm planning a job that will get done over many weeks/months and am
considering buying a small (say 3/4 ton) digger nth hand to sell on
when I've finished with it. I think this would work out cheaper than
hiring.
I want a tracked machine not a powerfab type. I don't want a complete
wreck but I'll consider something that needs a little TLC.
I'm near Southampton so something in the southern half of UK would be
preferred.

Anyone know of anything that might suit?

TIA

Bob
