I have not seen the HDR Hunt Bridle, but I wanted to throw out another possible option - Bartville Harness. I own 2 of the Bartville Harness Hunt Bridles. They are built to last, and are extremely good quality bridles for the money. They are slightly over the price range you suggested, $91.05 for the horse size, and $56.95 for 3/4" laced reins (both in the 2012 catalog). Their stuff is built to last, made from great quality domestic leather, and has either stainless steel roller buckles or solid brass buckles. If you are looking for a good flat working bridle that needs to hold up to hard use, they are just the ticket.
