Oh dear, did you go to a generic hardware shop?
Those prices are retail prices I believe, Choo chiang sells them at wholesale prices. You should really check them out.
Yes, the part about the LED is true, but LEDs in general can last for very long, but then there might be even better designs.
Another thing you have to take note, are you fixing these switches just the front panel itself or there's a fat box behind?
This nice switches wouldn't look nice with a box behind .... that's how I feel.
My ID had given me these MK switches. they may probably look nice if it's just the front panel, minus the yellowing box behind ...
But it looks generally plain and cheap, it's $1.70 for the one gang at Choo Chiang.
Asia Excel!
I like their services. I got taps, instant heaters and bidets from them.
I noticed the franke sink, but it was out of my budget, so I gave it a miss, much to my regret, it was perhaps another $100 more than the one I got.
My sink was from Chuan Heng (at Jalan Besar), it comes with an attached dustbin for convenience, it was a big mistake. Please don't ever get any sink like that ...
The leaking sink
I've sealed up that dustbin 3 times with silicon, doesn't work ..
Eventually I sealed it up completely with aluminum tape.
From a user's point of view, I would also recommend matt surface rather than shiny surface, because it's hard to prevent scratches on a shiny surface, water marks will be very obvious also. But that would be your preference, I'm just sharing my personal opinion.
