Check the listings for open box items at Best Buy. I found a Panasonic DMP-BDT310 at a local BBY - no remote or manual, but it had the dual HDMI outputs that I needed. Out the door for under $100. They are highly rated and still available new:

Another option is to find either a new or used player with 5.1 (or more) analog outputs that you could connect to your multichannel inputs on your denon.
The Oppo BDP 93 is at end of life, but still available from the Oppo site for $415 for a refurb...
Or, try this splitter from Monoprice - $25...
