Sony Notebook Parts - Delays and Options?

I have a Sony VGN-NW230G notebook PC. Over the past few weeks I've noticed the video cooling fan occasionally squeaking. Since it is still covered under MasterCard's extended warranty plan, I contacted the service dept. at the store where I purchased it (I would rather replace the fan before it dies and takes the video card with it ).

The store's service manager (although honest about it) gave me bad news: It appears Sony is having serious issues providing replacement parts (in or out of mfr. warranty) for VIAO series notebooks. He told me that - if the store could get the fan - it would likely take at least 8-10 weeks to arrive.

While it would be a mixed blessing if the PC suffered major issues due to a fan failure (MasterCard would have to cough up $699 to replace it), I would perfer not to go this route.

Does anyone know of a source for good quality aftermarket Sony notebook parts? I don't want to order junk; I want to buy from a company selling either in-stock OEM Sony parts or high quality aftermarket ones.

Any tips, ideas or parts sources would be appreciated. Thanks.
