If you plan on doing more SMD work, I highly recommend a hot air rework station and some no-clean liquid flux. With those two purchases, plus some aluminum foil and some Kapton tape I can pretty much take 99% of every component off a motherboard and put it back on again. I'd also love to give out advice and pointers if you ever wanted more
Soldering iron, hot air station and digital microscope make up the bulk of it. Im debating between a couple hot air stations that are $60 that have decent reviews.
