I actually quite like butane soldering irons, the freedom they give you is liberating. I have a Dremel Versatip ( which admittedly I don't use half as much as I should do ) which is great, the only complaint I have is that it's really hard to temperature control and it tends to get so hot that EVERYTHING melts. I think it's aimed more at jewellers and hobbysts than electrical tinkering. But damn does it ever look good and come with a lot of attachments.
I also have the Maplin 50W soldering station which, crusty looking though it may be, actually works pretty well. It takes what seems like an age to heat up, but once it's there it does a pretty neat job, and the hefty-base + combined solder stand make for a secure place to store your iron. It's not bad for £25, anyway.
With any iron, I'd heartily recommend throwing out your janky solder sponge ( if you still use one ) and replacing it with a good tip cleaner, like this one: http://shop.pimoroni.com/products/soldering-tip-cleaner
I think you've probably already outgrown the Antex ER-30 we sell. If you really want something that will last ( but costs about 4x more than Maplin's entry-level workstation ) the Hakko FX-888D or similar is great.
These are the irons we use in-house, and we'd stock and sell them if the boxes didn't take up so much room! They're temperature controlled, so you can set and forget, and we leave them turned on all the time so we know they're reliable.
