Asia - cheapest one-way flight within Asia from HKG

I am looking for a cheap one-way flight from Hong Kong after Christmas.

From HKG, the typical destinations are:

Bangkok (Ethiopian is cheapest @ HKD830 before taxes)
Singapore (United @ HKD900, but JetstarAsia has fares as low as HKD228 or HKD450 inclusive of all taxes this coming week Dec 13-20)
Beijing (China Southern @ HKD1160)
Taipei (JAL @ ~HKD1200)

Am I missing any one-way destinations that can be reached for less than USD200 from Hong Kong (and without having to cross the China border)?

Any travel agents to call (other than zuji.com.hk?)

Thanks.

The helicopter to Macau is HK$1200. Does that count?

you forgot about mnl (can be extremely cheap) and ceb, though i don't think i'd ever go to mnl for pleasure (it sounds like you're objectives are leisure-oriented, right?)

as for TAs, i like: http://www.wingontravel.com/

Air Macao to Seoul is cheap, but constantly sold out.
