I thought Scootbiz was fine - did SYD-SIN one-way on a Sunday in Dec-12.
OK, it's 2+4+2 seating, but it reclines enough that I can take a nap and it was adequate for a day flight. I also recall there was a separate check-in desk at SYD (no queue).
Now, I paid AUD807 all-in (booked 30 days in advance), so not sure if people would consider that good value or not.
