Actually a LiteOn DVD8900 but IIRC that’s a BenQ DW1670.
Keep in mind that it has a Panasonic chipset that doesn’t support DVD scanning and SolidBurn, instead DVD-RAM support. It can scan CDs though.
There are indeed some cheaper offers especially online but ARLT Computer have several stores in South Germany, and for B&M stores, this price isn’t bad (if you live near one and can pick it up there to save shipping costs and time ;)).
(Unless you pre-order online, they’ll charge you â‚¬ 29.00 though.)
