I use the solderpro 70 from Maplin.
It's on offer at the moment:

The standard tip you get with it is pretty useless, I would recommend getting the pack which contains the chisel tip.
On another note, it does come with a heat gun attachment but have found this is far too hot to do heatshrink, a lighter normally works well for me.
