I like Newegg

If you ever need anything computer-related, go to Newegg.  They are freaking awesome.  We've ordered from them several times in the past, including all our new compy parts, got several really good deals, and everything worked perfectly.  Then we ordered Netty's laptop from there and were equally pleased.  And then, when the firewire card we ordered with the laptop didn't work, they gave me a full refund, no questions asked.  I didn't even have to send back the defective card--they said to just throw it away.  And this wasn't like an "I'll have to check with my supervisor" kind of thing.  This was a "Yeah, it was only an $18 card anyway, and keeping a loyal customer happy is totally worth $18" kind of thing.  Good company.
