Go here for used Mac Books
This is where I got mine. I spent $1999.00 on mine. 17" glossy, 100GB/7200 RPM, best video card etc. Top of the line.
I recorded 20 tracks for 2 hours today at 256 buffer. Then I recorded an hour at 64 buffer with 20 track. My M6811 would never do that. It is just weired not know how to do things on the mac with the OS and Hard Drives but it is easy to figure out.
I got up to 75 Dverbs at max buffer while recording 15 tracks. That works for me....
