I don't have any experience with the Oppo but I've tried a few cheap DVD players, in the $50-100 range, as transports for a Benchmark DAC. While the sonics are fine, at that price level the build quality of the controls and transports becomes a frustration. I've been happier using one of the lower to mid-priced Denon DVD players. I've had both a 2200 and 2910 and been quite happy with that setup.
