ill answer my own question now that ive done the research and can prob help someone else, the best option is buying an Imac currently the cheapest compatible macbook pros are the 15" which need modifying to 7200rpm at that price even season clearance sale 100$ off or not, youre talking over 2gs.
The standard imac comes equiped with more usbs and 7200rpm the 4gb ram is more than enough, and costs like 800$ less.
Happy recording here i come!
