I am considering upgrading my Dell Dimension 4300 PC by purchasing additional memory. I presently have 512 MB (2 x 256) installed. I want to purchase qty 2, 512 MB to replace the 512 MB total I presently have as I have no empty slots. I have looked at the following:

From Dell $79.99 each

From Crucial $ 56.99 each

From Buy.com (eMartBuy - Elixir brand) $11.00 each

I know and trust Crucial, bu what is going on here? Is it a case of "if it seems to good to be true, it usually is"? Has anyone had any experience with this brand?

Any help would be greatly appreciated.
