What are you thinking about MSI Interceptor DS4200 ??

Overall reviews seems to be positive about it, doesn't mean there might be better ones though (apparently from looking at the poll results it appears so).
There are more better known brands for keyboards and mice though, up to you what you expect from it.

Nothing wrong with that, if you like that keyboard go for it, just remember that you are not paying a lot because it's a super premium product, but you are actually paying marketing.

btw, cooler master has a couple of keyboard+mouse combo with leds and stuff, I gifted the devastator kit to my borther (~30€), the mouse is uhm, okaish, the keyboard is actually nice, we are still talking about non-mechanical stuff, but the price is honest

Myself, I'm still missing the old IBM design with function keys on the left side of keyboard, It was so easy for me to use alt-fn, shift-fn and ctrl-fn with it. Since they have practically disappeared (was it caused by laptops becoming more and more popular?), I've practically stopped using ctrl, shift and alt with function keys, finding it very inconvenient with the keys located at the top. So, I guess, it all depends on what you are used to, and it certainly takes time to get used to a new keyboard layout.

They do offer however quite a few similar highlighted keyboards without the side keys, some of them even with RGB, in the same price range. So, choosing "cheap", Tracer is one of the best options, IMO, if it sells in your country. Same with headsets, btw.

Did you check on Ebay? Just look for Cherry G80 or G81. There still should be a few awailable. I admit, I probably was lucky to get a new one, but I'd even prefer a used one (as long as it's in good condition) over those Asian imports any day. If your system still has PS/2 you have even more options.

The K68 is a really good mechanical keyboard. There's 2, one with RGB lighting for $75 which is what I was referring to in my first comment and then they also have a red backlit one for $70 which is the second link.

Yeah, Corsair is my favorite by a long shot. I own two of them now (a K70 and a Strafe), because I dumped an entire soda on the K70 and rushed out to buy the Strafe since I thought the K70 was certainly a goner.

But ... I tossed the entire keyboard under the hot shower and let it dry a couple days, and it works like new.
