Hi!
I went looking for the screen and the link in the build guide lists it now at about 54€ https://www.ebay.co.uk/itm/113749676431
I found the same screen on aliexpress, slightly cheaper at about 46€

Both these prices are inclusive of VAT and shipping, so final price may vary depending on where you live, but I just wanted to share an alternative source.
From the dimensions and pictures these screens seem to be identical.
