Well I took the plunge and bought me an ST-237, so my webcam days are past. ;^)
I have a QUICKCAM VC neatly housed in a project box with a 1 1/4 inch nipple for astrophotography. No electronic modifications, just the camera housing was changed. And that was done by the gentleman I bought it from, so it was done right. Truly outstanding as a planet cam. Check out the QCUIAG website for more info on the QUICKCAM as an astrocam. I am asking $125 shipped, but will entertain any offers over $75. However, the first one with an offer of $125 gets it.
P.S. I will post some pictures of it tomorrow, if necessary.
