I just ordered a MacBook and plan on upgrading it to 2GB of RAM. I have 2 online options in mind. I am ordering from Canada.

1. www.crucial.com ($360 USD plus shipping, taxes, duties)
2. www.memorytogo.com ($236 USD plus shipping, taxes, duties)
3. www.macsales.com
- Techworks ($249 USD plus shipping, taxes, duties)
- OtherWorldComputing ($225 USD plus shipping, taxes, duties)
4. Other???

I don't mind paying for quality and stuff that makes a difference but there is a significant price difference here with some stuff???

I assume with the integrated graphics using system RAM on the MacBook, it is especially important to get good RAM. Looking forward to responses....
