I don't get these price discussions. If you earn your money by programming, I think it is crazy to be cheap on your tools if you can get the job better done using them.
If you program occasionally, then use some free open source editor.
People on construction sites don't use the cheapest tools available for a reason. If you use it to earn money, you shouldn't be short sighted.
If you tell me a Ford Taurus costs $40,000, justifying that by telling you I spent $100,000 on a broken bike doesn't make the former a good deal.
The way I see it, $70 on its own is meaningless. A lot of people are taken aback because it feels like $70 for an advanced text editor. And in many ways, it is that with some IDE flair built-in.
I own a license and honestly still find myself in Notepad++ for a bunch of things. As a professional programmer, I have come to the conclusion that for my purposes it's overpriced. Your mileage ... well, it should vary.
