Just want to give a quick shout-out to my favorite brand of computer keyboards, KeyTronic. I think they were originally a Spokane (WA, USA) company, and still have their U.S. operations there. Their keyboards are quiet, durable, they handle beautifully, and the Lifetime Series has a lifetime guarantee. The Lifetime (LT) Series sell for about $40. They're surprisingly hard to find: Amazon has them in their catalog, but may or may not actually have some available to sell. Some are available through zShops sellers. Thankfully, KeyTronic sells directly from their home site.

I tend to pound mine hard enough that the spacebar gets a tad unresponsive after several years of heavy use (I've had two KeyTronic keyboards develop this same flaw in the same amount of time). I just contacted them through their web site, and quickly got a response saying they will replace the keyboard with a newer, upgraded model if I simply send them the label from underneath the keyboard plus the PS/2 connector off the end of the cable. Sure, I'll have to make do with a spare while I wait for the new one to arrive, but still, that's damn good service.

I use the ever-popular Dell QuietKey at work, and I still prefer KeyTronic. The QuietKey is an excellent keyboard, and I can't think of any other brands that would compare to these two. But when I have a choice, I go with KeyTronic every time.
