Query: UPS getting wealthy

I am in process of returning my second sample of this unit. This is not my first burner, and my system and software are up to date. The first couldn't read an Imation disc it had just burned at only 4x (crashed with Easy CD Creator Deluxe 4.02e1 but I could use DirectCD 4.02d), and an hour with Yamaha tech resulted in a return. The replacement is completely dead- no power- after a 1.0H firmware upgrade attempt that failed while installing. Both sounded like string trimmers. I am going to try a Plextor- I can't stand to keep paying for continual trips to UPS. They're the only ones in this deal that are making out.
