I have been using this RAM card in my PowerBook 3400 for the past two and a half years without a hitch. I am selling it in order to help pay for my new Pismo.
This 128 MB card is name brand (Its either Kingston, Viking, or PNY. Haven't looked at it for a while.) and has a lifetime warranty from the manufacturer. Because of the high-grade of the memory, it was a little bit more expensive, but my experience has shown that it is definitely worth it. I think $300 plus UPS shipping and insurance (a must for components) for this card is not unreasonable, and I am a verified PayPal seller.
I would appreciate anyone who is interested in this item to email me at ian@primewave.net. Thank you.
