Aven 17010
I’ve been using the Aven 17010 for a while now, and I’m very satisfied with it, both for iron and hot air soldering. The Aven 17010 is also available on Digikey and Home Depot, for around $13.
Chinese Universal/Phone PCB Fixture
I first came across this PCB holder in the phone repair shops and schools in Shenzhen. This holder is fantastically simple and sturdy. And because it is made from metal, it works really well for hot air rework.
On AliExpress for around $4.
