Hi Troy. Been down that road also. The Philips cam just doesn't seem to have the sensitivity to pick up a guide star unless it is pretty bright and the DSI seems terribly prone to dust mites on the sensor. I gave up and bought a QHY5. But on another scope, I have just fitted a new device that is marketed as an electronic eyepiece and a 3 Meg resolution and it seems to be promising. It is a web cam style of device, like the ToUCam and therefore will work with programs like MetaGuide. But I have yet to give it a bit of sky. The moon is still too bright but I'm hoping that there will be enough time before it rises to give it a proper test. The device is made by a Chinese (surprise, surprise) call Jicheng or some such and has a serial number MD300.
I have had PHD recognise it as well and the picture is sharp and well-defined so I'm fairly confident it will work pretty well.
