Northern Norway, but there's a ton of variance in prices here. You can easily move tens to hundreds of thousands in one city, so to find the cheapest you really need to look hard. I found a relatively old and run-down place, but which was easy to fix.
With that said, I have a very nice salary - relatively speaking - but as mentioned, it's around half of what jr. Engineers make in SW.
I'm lucky because my background from both Business and Engineering has been a good mix for landing my current gov. job - and the pay is good because the area / location is not very attractive, and it makes harder to get talent here. (I grew up here, so that's no problem).
Work involves a lot of travel, and I travel otherwise during my vacations, so things rarely get boring.
I've worked all over the world, but after I turned 30, I really haven't had the big-city needs, so living somewhere rural doesn't bother me anymore.
