When you restock I'd highly recommend this brand.

If soldering yourself, don't forget to use leaded solder (63/37 preferred) and good flux. If you don't yet have an iron, my favorite is the Pinecil, it performs wayyy above it's price point, and can run off of a USB-C laptop charger/Nintendo Switch charger/etc. Oh yeah, and make sure to have a tip cleaner on hand, an oxidized tip is a huuuge pain. May as well pick up one that doubles as an iron holder.
