"This version is worth the time & money."4.0 starson by Fred Collie
Pros: Great speed and processing power
Cons: non-customizable face panel, no FireWire ports
Summary: After looking at the specs. I bought this for my son's schoolwork and found it a great buy. It was when I wanted to give him one of my burners, that I realized it wouldn't look good inside. So when I attempted to connect through the FireWire, I found none. Expansion ports fixed that, although I feel more comfortable using the burner internally. Speed and precessing power are great and I recommend this unit.
