Most receivers with SiRF chip set in the market don't support SiRF binary raw data output.
Do anyone know where can I buy a GPS receiver with built-in high-sensitivity SiRF chip set and output SiRF binary raw measurement data message ID 5, 15, and 28?
Cheers

By "high sensitivity", I presume you mean XTrac. There is some confusion - http://www.sirf.com/downloads/collateral/press_releases/SiRFXTrac%20Product%20Insert.PDF says SiRF binary mode is available, but many reviewers say it isn't. There are some features in standard SiRF software that aren't in XTrac - particularly SBAS (WAAS and EGNOS) support. Apparently one problem is that the processor is working very hard when running XTrac software - I'm not sure whether there's also memory limitations.

Unfortunately I don't have access to an XTrac receiver to check for SiRF binary support myself.
