Likewise, I've got an AOYUE unit but went for the 768 which has a very good soldering iron with fume extraction along with the hot air functionality.
It is an absolute pleasure to use!
I got it from buyaoyue.com
, and recommend them. They *might* be able to offer a discount - I did ask about offering a discount to eab and amiga.org and they said they'd consider it... However, they're UK based.
