I would have to say after my search newegg may be a few dollars more but there service is second to none which is what I look for. So I have to also agree with Newegg, I actually just bought some from them for my notebook and desktop, I went with kingston for the notebook(7700 Alienware) and Patriot for my desktop. Patriot uses infineon chips which is awsome and great price also. Kingston uses Hynix for there 512 chips. Good luck just remember to match brands to have a better compatibility with dual channel.
