Short DVD burner for Aspire X-QPACK?

I’ve heard Lite-On DVD burners are shorter than most, is this true?
Any certain models I should look for?
Other brands are OK, too - as long as they’re good ones.

Plextor PX-716A is also short.
BenQ DW1640 and plextor PX-740 is pretty short too, although slightly longer than Lite-On/Plextor PX-716A .

so Lite-On is the shortest?
any certain model?

btw, sorry about the crosspost :o
