I'm in sort of a similar yet different dilemma. I've owned a Microsoft Natural Keyboard Pro for 5+ years I think, and it has served me very well, but I think I've spilled one too many drinks on it, and some of the keys are starting to act weird. Unfortunately, Microsoft doesn't sell this model anymore nor do they sell any keyboards with USB ports in them anymore, which I've found very useful. So I started looking for a natural wireless keyboard, but for some reason, it appears that neither Microsoft or Logitech sell one that doesn't come bundled with a mouse. Why do companies sell so many of their keyboards only bundled with a mouse? They may think they are going to force people into buying the bundle, but I'm simply not going to pay $70-100 for a keyboard, even if it does come bundled with a wireless mouse I have no use for. I'll probably end up going on Ebay and picking up another Natural Keyboard Pro which appear to be going for about $20.
