I have a 09 MBP Lion. I want to upgrade my 160gb HDD to a SSD drive. I have 2 concerns. First is I want to know some advice on what a decent SSD drive to purchase. Second. How do I install Lion, I had downloaded it from the app store so will I have to re-pay for it again or once I get the new SSD installed and everything up and running with the disc that came with my computer, I can re-downlaod it once I am in the app store? Thanks guys.
