Worth the money!
For TC4+ Coffee Roaster Shield - TC4 PLUS
I ordered the pre-assembled version. In fact, as the SMD components would have been soldered on in the kit version, I would probably haven't had a problem assembling it myself, as good as all quality is.
The shipping was fast, though I experienced a delay thanks to Brexit and COVID. In this light, it was great that I could reach the seller, who answered quickly.
The part itself is very satisfactory. It's well thought-out, offers a lot of options, is very well supported in Forums and Github repositories, and has a community you always get help in. The written documentation comes in several detailed PDFs.
