I recently picked up an 936 from keisub as well and couldn't be happier with it. The only thing I would recommend is picking up the 5.2mm chisel tip for it. Hakko part number 900M-TS3/P . The tip that came with mine was a 2.6 and it just didn't transfer heat quickly enough for me. The 5mm tip makes a world of difference.
If you are looking for something cheaper I also own an old Ungar(now called Weller) chisel iron that has served me very well. I think you can pick one up for around 20 bucks or so.
