I have a macbook C2D 2.0ghz 1gb ram 80gb hd I do video editing and such. I am thinking about upgrading to a mbp. If i get about 900 from the macbook, and have about 300-400 to spend, are there any decent mbp's out there? Something better than my macbook of course, and it can be used or refurb. Let me know what to do, even if it means sticking with the macbook. thx.
