I'm just starting out myself, and have been looking @ outlaw too. In their "news" section they make mention of a new receiver that will have "As previously announced, it will have the full suite of Dolby and DTS modes, including Dolby Digital, Dolby ProLogic II, DTS 5.1, DTS-ES Discrete and Matrix and DTS Neo:6."

...so if you can wait (I think december was targeted release) it might be worth it.
