They're expensive, but COSTCO had/has them on sale at more than half off.
This is part of doing things right, generally - weighing up price vs. general usefulness and getting the most bang for your buck, so to speak.
Buying shit products because they're the cheapest is usually a total false economy in the long run.
(I'm building a new computer from ordered parts to try to save some dollars, and while looking at power supplies today, I came across a 1600W one for the same price as 500-600W ones of other brands. So I looked that brand up online, and sure enough, nearly all the comments said stuff like, 'Buy this brand if you want all your other hardware to be fried' and 'If you're going to buy this brand and use it for anything more than a stripped-down word-processing running-something-like-KolibriOS box, there's gonna be pyrotechnics!'
So there's a good example.
Shit, at my age, the prospect of only needing 2 or 3 more lightbulbs per socket for THE REST OF MY LIFE in my house is pretty exciting.)
PS: and seriously, do check these out, they are great for old computers and computers you don't use for very graphics-intensive purposes...
