Good things are not cheap, cheap things are not good. In general I either get the most expensive or the cheapest. No point getting the middle.
One thing I learnt in Australia is that there are 2 ways of doing things - the cheap way and the right way. If you opt for the cheap way, you get yourself into problem and blame someone for it.
To me, the evaporative is an American "stop-gap" product that does not solve problems.
Perhaps Singaporeans like the product because it give a humid weather, but you will notice after a while that the dampness from evaporative create bacteria, mildew and give a musty smell. Also, it worsen asthma allergies, and cause some white furniture to turn yellowish.
But wait, the Americans also create another product that try to solve this problem. But whether it works or not - back to my first question. There are 2 ways of doing things.

Oh, another point. The evaporative is also known as swamp cooler because it gives off a fishy odor when Perth is humid.
Then, I have the same issue with flood lights. That simple thing you think. My tenant bought one costing $15 and almost burnt my property down. That is why I tell my property manager - go get the $40 one. It is a proper product with safety certification. My insurer will not complain either.
There are a lot of things like that in Australia. Because of DIY, people buy cheap stuff, take shortcuts and then wonder why they spend so much time running around getting things fixed.
This is commenting from experience. Things are cheap for some reasons, if it is goog value, go ahead.
