I'm going to buy the stock 2.2GHz MBP with a hi-res screen and I want to do my own upgrades. These are the parts I was thinking of getting: Crucial 8GB RAM ($79.99) OWC Data Doubler chassis ($74.99) OWC Optical Drive enclosure ($39.99 w/ purchase of data doubler) Crucial 256GB M4 ($459.99) I've read mixed reviews of the OWC Data Doubler. Most people say it's too expensive for what it does, but the other solutions I've found look cheap and flimsy. I'm especially unsure of the SSD. I read through several reviews and the Crucial M4 seemed to be the best speed/size for the price. There are also different models of the 256GB M4 but I'm not sure what the difference is. Is there anything better/different I should be considering? Any other general advice? Thanks!
