I have stopped going to auctions.
By the time you have reckoned travelling, not being able to run machines under power, buyers fees of up to 22%, plus VAT on the lot and no guarantee you are going to get what you are looking at, see the examples above, it's a waste of time.
Last time I wanted a piece of equipment, which was a 12" rotary table, I advertised for it, let them come to me , in principle, not physically.
I got decent replies and had the choice of 4 items which I could then choose based on cost, condition and where they were, and nobody snapping at my heels. Chose one in Coventry, 45 minutes away for the princely sum of £25, no fees and no VAT.
