New soldering iron needed

My old Weller soldering iron station (an old Pye Telecom chuck-out from about 1980) is on its very last legs - it is physically cracked and really does need replacing. You can tell how old it is by the mains wire colours! It was possibly the one I had on my bench when I started work in 1970.

I'm looking at the Maplin soldering iron range for a replacement, which look good value. Most of my work is with discrete parts but increasingly some SMA parts are being used too. Up to now I have been using up my stock of tin-lead solder, but am happy to move to lead free.

So, please may I have your recommendation on what soldering iron to go for?

I don't mind spending a bit more if by doing so I get a more reliable soldering station. Clearly replacement tips must be available inexpensively.
