Okay, sorry for being slow (very slow) to respond to your queries; for best results, sms nalang (0917 7945003) or email (richie @ ehome.com.ph) or call (7445923).
Anyway, the 34a is currently at 8k group buy price. It will have DTS support (which will be available on the next firmware update -- cross your fingers).
The 34a supports internal drives via it's own proprietary cable (like a mongrel female to male power/sata cable) but you'd have to sport your internal drive naked. This way, you can still have NMT apps installed.
The 34a also shares the same firmware as the 31b, but it does not have EXTERNAL sata. It has 2x USB 2.0 ports though.
Estimated time to arrival is late this week or early next week (better bet); best to place your 'orders' ahead of time.
