I'm on the lookout for a FHD IPS screen for the T420 that is compatible for max 150$.

Where do I source those?

I got a few displays from aliexpress, all of them were good quality. If the seller has a good rating, they'll most likely send legitimate displays. You'll also need a FHD adaptor. Together the adaptor and the screen will easily be under $150.
