Most people value a Hilton point at $0.005-$0.008 each and most people consider it a great use of points if you are able to get above $0.01-$0.012 per point of value out of redemption.

An example of an upcoming point redemption. The conrad in Dublin is 40k points or $475 USD. That is $0.011875 of value per point.

Everyone has different ways to value their points but I would not spent 40k points on a $200/night hotel. It is better IMHO to pay it and earn more points to use later. You might check to see if you are able to use a buy 2 nights get 1 free certificate. I haven't been able to use one yet so check before you order one.
