Thats a pretty good price for one.
I normally bundle zeddies with missing PSUs with one of these:

It is a repurposed PSU originally from CPC so presumably a safe option.

I thought the price was pretty good myself considering it falls into the vintage category.
There's nothing wrong with those aftermarket PSUs, but I want to keep my setup looking as original as possible, even though the inside of my ZX81 is far from original.
EDIT: Mine arrived and it looks so new that I suspect it may have come straight from the original factory via a time machine. Amazing!
