Lite-on IHAS324-08

Looking to pick up this Litey, noticed different retailers selling model has different digits ending.Eg. Newegg sell it as iHAS-324-98 , whereas another store sells it as IHAS324-08 . Are they identical burners with different firmware?:confused:

At Newegg, the 324-08 has the MediaTek chipset, the 324-98 should have the NEC chipset (same as Optiarc 7240S).

What is the best???

I have found ihas324-32—> nec or mediatek?

the best is mediatek?
