I paid $510 for the Asus UL20A-A1 last December, on an Amazon promo priced at $585 with $75 Amazon gift card included. It looks like Newegg has it NIB for $575 or open box at $452 right now. I upgraded the memory to 4GB for ~$40, but haven't bothered with a SSD. I chose the UL20A-A1 over other makes/models specifically for the SU7300 processor. The SU7300 supports virtualization and has an extra 1MB of L2 cache compared to the SU4100.
