My 3500A was doa. Power plugged in and not even a blink of a light and door will not open. Newegg just gave me an RMA for a 100% refund. Here is my dilema the Sony DRU 710A is on sale here for $99 after rebate. The NEC 3520 A is available at Newegg for 62.99. Will be late next week til piece arrives and with Sony I can pick up local and have done. NEC 3500A does not appear to be available any longer. It is off Neweggs site. Any opinions?
