Sean, how do you define low-cost? A couple progressive-scan changers that have gotten a lot of press here recently are the Panasonic DVD-CP72 and the Sony DVP-NC655P. A search should prove helpful. In case it matters to you, the 'CP72 plays DVD-Audio discs. In addition to conducting the search, check out www.crutchfield.com for more on these two changers as well as other models. Kenwood recently released the DV-6050 progressive-scan DVD-Audio changer, but I have not read comments about it, good, bad, or indifferent. Best of luck in your search.
