Did you know you could submit your request for product support to Microsoft online? And, if you do this and you have allready used your included suppor tickets... it's $150 cheaper?
http://support.microsoft.com/gp/assistsupport - Pick a product, in my case VS 2005, and then you'll see this page.
I honestly didn't know this option existing before visiting the Developer Support center this week. I honestly don't know why more people don't use it. Most of the engineers here seem to think that this is less than 10% of thier volume, but it's a cheaper option for the customer. And often times, you'll get a call back from the support engineer regardless of which method you submitted your request.
In the next year I'd love to see if there is a way we could simply give people an option to "escalate" to support via a cheap method like this from our community support options like the http://forums.microsoft.com/msdn if you don't get an answer from the community.
