Soldering/desoldering station

Looking for suggestion for a station around 5-600. I have my 3 channel Hakko that I keep at work for cluster repairs but want a setup for home too. Any suggestions? Thanks

Re: Psom circuit help

The only difference I see is there is an a adjustable pot on the original board. The working board is marked with an X.
