Advise me on which MBP for Logic Pro 9

[slugware]

Hello,

I bought a copy of LP9 from a friend and now i am looking for a used mac book to use it.

I am on a budget and have these 3 models as good deals right now


Apple MacBook "Core Duo" 2.0 13" (White)

Apple MacBook Pro "Core Duo" 2.0 15"

Apple MacBook "Core 2 Duo" 2.4 13" (Mid-2010)
http://www.everymac.com/systems/apple/macbook/specs/macbook-core-2-duo-2.4-white-13-polycarbonate-unibody-mid-2010-specs.html

on the third listed here, the white, 13", mid-2010 i am even offered to get RAM upgraded to 4gb

Please, share your experience and knowledge, and advise me which one would be the best of these 3 models, as i don't have any experience with apple computers whatsoever.

Best regards!
