so does any1 know ??
You can find and buy easily. I've already bought and installed it (512 MB Kingston). And now my memory is 1024 MB. Results are perfect and I have no problem about my computer (VGN-B1VP). Moreover, you can look this link more info about memory upgrade. http://www.vaio-link.com/tutorials/memory/memory.asp?l=en&category=-1&serie=-1&m=-1
But if you want to have 1GB you should be ready to by 2X512MB as Sony occupied both memory slot with 2X256MB. 
Or even Kingston
