I really need to work with my boss to see if I can get the organization to cover some or all of the cost to attend PASS one year.  In the precons that you linked to, there was at least one that I could point to as being relevant to my job, and I'm sure there's plenty of sessions during PASS that would be relevant.

As it is, I've got attending PASS on my "travel bucket list," I figure the wife can find things to amuse her while I'm at the convention...
