Common ones are the x2 4981.07 (>137GB F: drive), 4981.67 (137GB F: drive and rest on G:) that's if you have a hard drive that big of course.
And the other would be the EvoXM7
I think if you want to be able to put the matrix chip in mode 3, which allows you to disable the chip for live then go with EvoXM7, because i had some problems with that when i was using x2 4981.67 that's when i had the matrix chip.
Personally i like both about the same. Have pretty much what you need.
