I am a keyboard nut and have tested practically all the keyboards out there. Almost all of them are mushy, even the MS Bluetooth, but I found one exception, the new Compaq keyboard
. Positive and silent unless you are a hard typist, but then it becomes even more positive and solid to the touch in a way that reminds one of the old IBMs and Northgates, noise and all. Its companion mouse is just OK.
Not sure if this is the one you are talking about:

I picked one up at CompUSA for $20, and it is definitely a lot quieter than the one I had. It is possible to type very quietly if you apply very little pressure. Even typing hard, it is more quiet than the one I had, though. I don't know how it compares against the PSK-5000, because I wasn't willing to buy one mail order for $40 to find out.
Best thing is that it is a completely standard layout - identical to the Dell wrongly named "QuietKey" that I use at work.
Only found a PS/2 version though.
Now if I could only find a way to silence the buttons on my MX510...
