The rule I follow is 

2x RAM when physical RAM is 128MB or less;
1x RAM when physical RAM is 256MB but greater than 128;
never a bigger swap than 256MB

In monitoring, I have never had my swap usage get above 80MB when my physical 
RAM was 256MB.  When I increased physical RAM to 512MB, I never use the 
swapfile at all, and I run a lot of stuff at the same time.

Once you get past 256MB, you really don't put enough stuff in memory to 
require a swap file at all (for desktop use anyway).
