Our partner, Macway, now offers an external DVD burner which could be an alternative to the MacBook Air, which, unlike Apple's offering, works on all Macs with USB 2.0 ports.
The unit is based on the Panasonic UJ-870, and is capable of burning DVD 8x and 24x CD, not to mention Dual-Layer disks. The device costs 74 (~$115, £60).
