It cost me $36.99 + $3.99 S/H (if I had ordered 2, the S/H would be Free).
Lifetime Warranty.

I have a Sony Vaio PCG-FX210 that has 2 x 256MB PC-100 "low-density" SODIMMs from Crucial installed. They both work in the TP770X, also
The above 256MB PC-133 SODIMM also works in the Vaio PCG-FX210, as it is the upgrade for this laptop.

This is an actual upgrade for my Vaio PCG-FX210 that currently runs 2 Crucial 256MB PC100 'low-density' SODIMMs, as Crucial does not sell PC100 SODIMMs any longer.

This PC133 SODIMM works perfectly in my PCG-FX210 and in my ThinkPad 770X.

Hope this helps.
