I have been watching the price of the 4GB DIMMs on the OWC site. In the past 2 weeks or so, I have seen the price fall over $120. Does anyone have any idea what a good price is for a 4GB DIMM? Seems like there must be a huge markup to have it dropping by $20 every 4 or 5 days. I would love to upgrade my new MBP to 8GB, just wondering when the price might stabilize a little bit.
