I've been happy with mine from Tai Pan Row Men's Tailors although prices seem to have gone up a few hundred dollars (their headline price for the suit & dress shirt is now $4000).
when we got married, my hubby had a tuxedo made to measure with a chinese type collar. it was great! we got it from the "wedding" building in mongkok. back then(2000) it was $1400. not sure what prices will be now, though.
