If you include tax, the CenDyne is $66 less (after $50 rebate though) than
what I paid for the DRU500A ($228 inc shipping, NO rebate needed).
I don't care about the dual (-R/-RW and +R/+RW) support advantage
of the Sony that much, but I do like the fact that the DRU500A burns a full DVD-R in 15 mins, as opposed to 30 mins for the CenDyne.
If they both wrote to DVD-R at the same speed, I would cancel the 500A order in a heartbeat, since Dell messed up the shipping sequence in a big way, and could not provide any explanation as to what went wrong...
