Digital Blue QX3 microscope
If nothing else - I'll use this journal as an archive in the hopes someone may be able to use some of my research to their benifit - I'll add new "interest keywords" as I add new data.

I purchased a Digital Blue QX3 microscope from Ebay for $50.
Retailers list price is about $100.
Having played with many low end microscopes as a child, I guess I'm a bit spoiled with the magnification and resolution of the images saved from the Digital Blue QX3 microscope.
You won't get the detail or resolution with the QX3 that you'll get with a low end optical microscope (100X-600X).
Though the magnification is fair (10X, 60X and 200X) the display on the monitor seems foggy or slightly out of focus with digital imperfections. The only image size that can be saved from the QX3 is 512 X 384 pixels. These images can also appear out of focus. I have found however that reducing the size of these images to about 120 X 100 pixels will produce a large sized thumbnail with fair resolution.
Saving graphic images of what is being observed is substantially more involved with an optical microscope. The QX3 has the ability of instantly saving still digital images or videos of the specimin being examined.
Observing microrganisms is hard due to their movement. Many protozoans move very quickly and the video on the QX3 has trouble keeping up with the movements.
The video capibilities of the QX3 are poor. This may be dependant on the speed and graphics ability of the computer being used. The test model for this critique is a 450 Mhz with a 3D graphic card, 256 Megs memory, 16 Megs video memory.
Adults will want to turn the computer sound system down as the QX3 software comes with many annoying sounds that can't be disabled. Children however do seem to enjoy the sounds.
On the plus side, the QX3 can produce fair images of inanimate objects when the images are reduced as described above. The QX3 has a built in lighting system that provides upper and lower light sources (backlighting and overhead lighting). The lights are controlled by the software on the computer.
The QX3 seems to be an excellent way of introducing microscopy to children. The software is easy to use for children as well as adults. It's great for viewing common household materials, food samples and outdoor specimins such as insects and plant parts. It holds the interest of children well and the graphics software included with the QX3 software provides for interesting manipulation of saved images.
So was the QX3 worth $50 - yes - absolutely. It's probably also worth the $100 retail price. The system is geared towards children but proves to be interesting to adults as well. Even with the "cons" that were mentioned, the QX3 wil provide for many hours of family entertainment with an educational background.
