Ahoy, I read through the buying, installing and testing sections on here, very helpful. Now I'm actually looking to pick up 8gig for my mid 2010. Most of the recommended sellers have it for $250-$270 Crucial is $260, MacRAMDirect and Ramjat are $250, MacImprove is $220 but Transintl is $180. All of these are listed as being good sellers on the buying guide so I'm wondering if anyone has any feedback on the Transintl, since is so much less than the others I'm questioning it, but if its good quality then its a good deal. Thanks.
