Welcome Starbaby84.
Agreed that $173 is probably going to be the best you'll get. I advise booking it ASAP. It could be either 1) a special one-day fare sale on that route or 2) a mistake (ask TropicalFlyer about the fare from HNL to CDG (Paris) for something like $200 or so)
My new favorite site for fare comparisons...

It is a very powerful search engine. You can specify to include airports within (X) miles of either your departing or destination airport, and it will break down fares in all sorts of ways.
