Memory To Go? Online retailer any good?

A Canadian here getting ready to order new MacBook or MacBook Pro. Just checking out online retailers for memory upgrade. Anyone used "Memory To Go"? ( www.memorytogo.com )

Good? Bad?

Other recommendations that trump this suggestion?

Can't help on Memory To Go but I just got an iMac & bought 1GB from Crucial (http://www.crucial.com/index.asp) I had seen other people suggest them.

Yes indeed crucial makes excellent memory. I guess in this case you get what you pay for?

1 GB of memory at "Memory To Go" costs ~$100 where as 1 GB of memory at "Crucial" costs ~$200.

Thoughts?
