Those auctioneer T&C don't look too bad, but some want you to show evidence of insurance, a Method Statement for removal, and all sorts of other onerous things, so if you look at something from another online auctioneer, beware.
I believe Apex have difficult T&C, for example.
As for moving costs, my Boxford 330 I bought in June was in Liverpool, a 450 mile round trip.
Steve at Landylift quoted, IIRC, around £450-500 for collection/delivery to me, which was fair enough (but 20% on top of the cost of the lathe), but in the end I bit the bullet, hired a Luton van with tail lift and went and got it myself.
I stuck the Boxford on castors, it went on and off easy – 400kg but two of us pushed it on and off easy – all in cost of transport was around £180.
