Dont buy it just yet, I bought the newest samsung 64gb ssd drive on ebay (only 1 seller!) and I installed on the sr mbp. The ssd ran very cool and no noise at all and was a joy to use, I loved every bit of it boot time was very fast and app launch even 10 simultaneously launched each individual apps without interfering each app's launch time. And boot time was just under 24 sec.
But as mentioned above for some reason when I put my mbp to sleep it works fine but once you mess with the sleep options such as when you first install the ssd drive osx will have the virtual memory checked and sleep would wake instantaneously and worked real well. but after you unchecked the use secure virtual memory, all of a sudden the computer will freeze evertime you put it to sleep! Even checking the secure virtual memory back still didnt resolve this issue. I've installed leopard over 7 times to try to figure out whats causing this and tried even tiger. Unless you dont want to mess with your sleep/energy options after you install leopard/tiger the ssd could be doable. Also Sometimes it wont even wake up from sleep and other times it will wake up but once you open an app or even safari everything will just freeze the whole computer.
So in the end I sold it (for more than I paid for, kind of ironic) and I'm more than happy with the hitachi 7k200 that I originally had. Surprisingly from only the boot time was much noticeably faster than my hitachi but in almost everything else felt exactly the same.
