Logitech Z5450s....no longer in production...but I love the sweet retro looking receiver.
The x-armor is great. Brown switches so its a good compromise for me for the tactile feedback and not too clicky. Only problem is that the LEDS burn out. That sucks.
That's a shame. The retro receiver is what caught my eye. Time to set up a new eBay alert.
Good to know about the LEDs. Thanks!
