Digital Eyepieces for Microscopes?

tfiedler asks: "I'm trying to find a low cost digital eyepiece for my microscope, around $200 or so in cost, and have ran across very little useful information. I want something that can be plugged into my video capture card, so RCA or S-vid output is a requirement. I've found the following two products. The barrel for my microscope is 18mm in diameter. Does anyone have other suggestions, or any experience with the ones at the mentioned URLs? Additionally, has anyone done anything like this with a webcam?"

What kind of applications?

What kind of microscope will this be, standard or inverted? Will you be taking snapshots or full motion video? What will your lighting be? Brightfield, fluorescence, DIC, Hoffman correction or what? Will you be trying to take long shutter speed high gain exposures to capture fine details in low light? Does your microscope have a camera port built in or is it a bare bones "student" microscope?

I'd start with what I expect in an image and build a system from there. If you just want to take simple pictures of things close up you might also consider dumping your current microscope and going with this.
