I have a Digi 002 - I set up ProTools back in about 2003 and kept upgrading through version 8 (I did not like 8 as much as 7). I had this on an XP computer with a Pentium 4 processor. I would like to rebuild a new Protools studio - most likely based on Mac (if I can find a decent used one). This is for a home studio - so I don't need to be tracking full bands. I will use drum machines or loops and play everything myself. Mostly I am just looking for a stable system that I won't have to tweak constantly or worry about error messages. What is the most cost-effective MAC-based Protools solution now? Also - please tell me the approximate cost, including iLok, etc. I already have mics, preamps, remote hard drives, etc. I would need new monitors.
