I know the answer is probably no, but is there any chance of getting a hold of the GT425M found in your HTPCs even as a spare part?

I have an Acer aspire 7738G which has an MXM-A slot, while type B cards are easy to source, A tends to be a pain in the ass.

I know you could not guarantee compatability in any way shape or form, but could I get one as a spare part? (Found in the Vision 3D) And if so how much it would cost?

Thanks for your time.
