firewire is why i bought my liteons as well, also the fact it writes (well mine do and i assume the model your looking at claims to be All Write) eg -r +r etc.
Actually i bought it for this
you can make VCD, SVCD, AUDIO, DVD-R/RW, DVD+R/RW discs and firewire, component 576P, Fibre optic 5.1 , composite RCA L/R /V(yellow) front input and a few other features i cannot remember.
Not sure if the model your looking at has everything i listed.
Pity there was no vga output on either of mine.
Go on buy it
