Looking for 4gb of RAM for my new MacBook..

Can you guys point me in the right direction? I just bought a 2.1g Core 2 Duo MB w/ 120gb. pretty much the bottom of the line notebook but so far it does what i need it to.

What brand should i look for? Dual channel or regular? Or do i have a choice? Any links to products or any advice would be greatly appreciated.

Is this the right idea?

I'd suggest this. The first listing (OWC) less expensive, and nice reviews. Works great.

Go the easy way and scan first. Then shop around!

Another good place to go.

thanks guys

another question while im at it... are all the 4gb sets dual channel? or does the title have to specify dual channel for it to be? i notice some brands say they are and others do not.

forgive me for my ignorance. computers are really not my for-tay. nor is spelling .

google crucial

they tell you which type of ram to buy based on the model of you macbook and the quality and service is on par with that of newegg....minus the tax (If you live in jersey...like i do)
