Take a look at South Horizons. Apartments there may be a bit old and around the same price as DB, but you can find 3 bedroom apartment for under 30 thousand no problem (maybe even with seaview as well) and transport is very convenient (MTR to Central takes around 20 minutes). There are plenty of facilities available for use (badminton court, squash, tennis courts etc.) which are cheap; playgrounds for children as well. Shopping is also convenient (there's a big mall right across the road and a cinema as well!). Unfortunately you can't have pets as they are not allowed. If you would like to have a place on the island and not too far away from Central, seriously consider this, it's a great place to live (in my opinion)
