500Mhz spacebar failing?

[Steve Martin]

My spacebar startedmisbehaving today. It seemsto "travel" normally, but 
I really have to makesure I give it a solid push to make sure it gets 
seen.  (As you can see, it is annoying enought that I don'tgetthem all).

I've popped it offand cleaned out underneath it but it didn'thelp.  Any 
cleaning ideas? Sources for cheap replacements,etc.?
