I've been shopping around for keyboards, and randomly stumbled on this keyboard for $91 + free shipping. (YMMV for taxes.) I was actually bidding on a used MX 6.0 on ebay and lost, it sold for $85 shipped...I am so happy I lost. I can pick one up brand new with warranty from a reputable dealer for $6 more
This retailed for ~$200 a year ago. I think only remaining stock is being sold now.
This is one of the fastest keyboards built. RK technology. Great for FPS. MX cherry reds, so its linear with no clicky sounds and a 45cN, so depending on your preference, this is exactly what you want or the wrong switch. I like reds. Metal unibody construction. I personally like the aesthetics of the board. Its also not too large. Full N-Key rollover - all keys are read simultaneously 100 % anti-ghosting - no inputting errors. The magnetic wrist rest is a nice feature. Keep in mind, no macro features. This is also not your typical RGB keyboard for rainbows and unicorn lovers, which is pretty much what you can get from other competitors in the same price point. Often, the switches are not cherry or the construction is all plastic, or its just ugly etc.. Certainly personal preference though.
ONE ADDITIONAL TIP:
If you have never used google express, you can get a coupon code for 20% off your purchase and buy this keyboard from frys, through google express, and save even more money.
