If I do decide to go for a different scope I have some more questions...

Binocular vs. trinocular when using a microscope camera: Does anyone have experience with both? I guess the difference is that with binocular you have to keep taking the camera out to use the other eyepiece, correct? Any other differences? Is it really that much of a pain? You can still use the vacant eyepiece to glance through, right?

Megapixels. I think I'll avoid VGA (0.3MP), but is 1.3MP ample for making fairly accurate measurements and pretty images? Will I want a reticle to make measurements too or is it satisfactory just measuring digitally?

In fact, with a decent digital display, will I want to use the eyepieces much at all or could I just have it plugged in all the time and work from my laptop? Perhaps it's worth investing more in the camera and going monocular?
