Zach brings up a good point. The AD/DA converter isn't exactly the only thing you are going to need when it comes to monitoring as you will need some way to control the level going out of the D/A. I think Zach's concerns about the monitoring could be addressed with the Presonus Central Station as it would provide two headphone outputs with dedicated level control, line outs if you ever want to use a headphone distribution set up (doubtful if you are only recording two tracks by yourself), and also monitor control for a few sets of speakers. It also gives you two more channels of D/A via SPDIF or ADAT which may be used to switch back and forth between your mix and a reference CD.
Having owned both the Rosetta 200 and the Rosetta 800, which I currently own, I would probably say go for the former unless you plan on ever recording a drum set. But be sure and budget about $350-$500 on the Presonus, depending on whether or not you want the remote. It was personally recommended by Dave at Apogee, and I couldn't be happier with it.
