I wondered the same myself a year or so ago, spent way to long looking on google (may well have started a thread on here too).
after much pontificating I gave up trying to spend heaps of cash and bought an antex xs25 which I think cost me 25quid at the most. I then bought a few different sized tips and a better stand (with a wire wool cleaning pad). maybe 35quid all up inc the iron itself.
its definitely one of the most useful things I’ve bought and I quite enjoy playing with it. if you want to do components on a board I recommend buying some kits from china off ebay, 99p easily buys something with enough fiddly bits to get some decent practice in with.
if I had to do it again I would spend the extra for the version of the xs25 with a silicon lead.
