Keith, glad to hear you are enjoying the switch to PC land. I am headed in that direction as well.But Im getting mine from ADK, a turn key system builder and users of CS6. I had a lot of questions relating to both Premiere Pro and the PC. The have been very helpful in customizing one to my specific work flow needs. I did spec out a top of the line Z820, but $14,000 was a bit more than I wanted to pay. :D
