Irodo seems to have taken over from Antex for Gas soldering irons from what I gather, I have an Antex Gascat 70 soldering Iron and the replacement bits from Irodo all fit it, also the new Irodo soldering Irons all look 100% the same as the Antex ones that used to be on sale which no longer seem to be sold/manufactured, the only difference is that they are blue and the Antex ones were yellow....
I only use Antex Electric soldering Irons, they are the best ones I have used and I like them, have been using for years now, and I have an Antex gas one, the Irodo Gas soldering Irons are good, they have them on special offer in Maplins every year around this time, I get a maplin special offer booklet in the post a few times a year and I'm sure that the gas soldering irons are on offer at the moment...
for heatshrink I use a small gas torch instead of the heat attachment on a soldering iron as it has a bigger flame, I have one with Flame master printed on the side of it, I bought it in Maplins years ago and it fills up with the yellow tins of lighter gas....
at full price the soldering iron kit is about ÂŁ40 and on offer its about ÂŁ15.....handy to have one in the toolbox for when you want to tin something or solder a tag connection or the likes....
