I've got that soldering station, Cris. The tips are quite thick, which is a good thing as they last longer. I've only had three grumbles so far and they are:
1) Maplin seem to stock the replacement tip packs sporadically so it is wise to order a replacement pack before you need it. Also, they only sell a pack of 5 assorted (and the iron comes with just one tip, a medium) so if you only use one size, it could work out rather expensive.
2) Maplin don't do a really fine tip in the pack. Having said that, the fine tip they do supply is just about okay for SMT stuff.
3) Their web site is pants.
