You may have already found a suitable unit but in case you haven't I can recommend a soldering station that was sold by Maplin (may they RIP!!).
It was called the Precision Gold, not a name that that sounds very confidence inspiring but actually it is quite a good unit, and I speak from personal experience. It is fully electronically temperature controlled with 3 temp preset's. Quite well made and is still available under other names, which unfortunately I don't know. They appear on ebay now and again, generally for around £30, and at that they are a bargain.
I still use mine occasionally, even though I now have a Metcal! Oh yeah, tips are still available.
