Sites to buy from

ok so I did my research just to make sure I was not posting the same thing again

I have a

Macbook Pro

2.33 GHz intel
2 GB ram...blah blah and so on

i was trying to figure out what sites are the best to buy from
as far as components go

upgrades/replacements

any suggestions?

For memory upgrades and hard drives I'll say Newegg.

Other World Computing is awesome too. Very efficient, professional and friendly service.
