Euro IIe PSU - Options/-12v?

As detailed in another thread I have a euro IIe which had a RAM failure and also has a burned transformer in the PSU, so I need a new PSU. I like the look of the Reactive Micro one but the price is a bit high and the shipping to UK is almost the same again so that's out.

I've done some research and it looks like the IIe doesn't use the -12V rail at all unless a Unidisk is connected - is this true (I have a spare Mac LC II PSU that does +-5v and +12v and would be a great fit if so...)?

 

If I do need the -12V rail, does anyone have any suggestions for Meanwell-style replacements? The suggested Q60 and Q75 options seem to be discontinued and I can only find clones of unknown quality on Aliexpress.

 

Thanks for any advice.

Some other cards and the keyboard encoder

Some other cards, i.e the Super Serial Card, want to get -12V. Also the keyboard encoder need to have -12V.

 It's not cheap, but it is by far the best option for an Apple II power supply:  https://www.reactivemicro.com/product/universal-psu-kit/

And it works from 90VAC - 264VAC input, so it is truly worldwide universal.
