So .. the first analysis is:
... have I over paid, and if so where? - I feel very little, if any, buyer regret - yet I'm not entirely satisfied with my lots.
The prices, which I've indicated below, includes my travel expense to collect the lots and a small bank travel expense - no personal time, which I would not have added to an account of this personal purchase.
.... the HP3400A came in at £159.17 - that feels high - it turns out that the item is not the sexy classic version - I'd missed the lack of a zero dial adjuster on the lot photograph. So it looks like I have a late version - not sure yet what else it needs to be fully operational.
... the Kikusui PMC 18V 2A came in at £95.50 - no bargain, but not so pricey for this type of power supply - the fuse has blown, may be by me powering on with the power button left on
... the three small torque wrenches came in at £57.60 - they're used but look and feel quite functional - in quarter inch square and hexagonal drive - no obvious complaints or worries there.
... the Robin 3131 insulation and continuity tester came in at £50.02 - that's on reflection a bit more than I'd've liked - but the Digimess DP3005 linear PSU was just £40.93, a probable bargain.
... the three Beckman Industrial HD110 multimeters came in at £48.51 - so about £16 each. I'm now warming to these "Egon Spengler" possibly Ghostbuster DMMs- after various
Ali Baba [Aladdin] cleaning treatments. One of the three is missing a 10A (?) big fuse, but one of the other ones tried with a fresh battery was quite impressive.
