We are buying a 24" iMac with 1GB RAM, then buying 2x2GB RAM after market (see choices below) to replace the 1GB of
RAM. This should save us $600! 
QUESTION:
Is there any difference in QUALITY of these?
The Micron & Samsung both say "Factory Original"
1) DMS $198
2) OWC $180
3) Techworks $195
4) Micron $210
5) SAMSUNG $296
___________________________________________
I was thinking about going with the MICRON @ $210
just because it was "factory original" and made in USA.
