I have no experience with the butane jobs, but I like the idea of using something better than a bic while under the dash playing with heatshrink. I'll have to look into that portasol
For bench mounted, I have a
Weller WLC100 which is wildly popular on Amazon. I would buy something nicer though in hindsight. The Hakko's are very well thought of in the mid-price range and will likely be the Weller's replacement even though they look like Fisher-Price "My first solder station".
If you can find one second hand, the weller ec1002 is a huge improvement over the wlc100 and I have a buddy that swears by it.
Also, don't know what tips the hakko takes, but you can find weller tips everywhere, even sears. So if you like the ability to get tips on a sunday night, get a weller.
If you're hamfisted like me, buy yourself the little third hand arms. They're annoying to setup just right, but allow me to make better joints. This guy made one with coolant flexy pipe, and I aim to copy the design:
