I just purchased a Nikon SMZ645 Stereomicroscope off of eBay for surface-mount inspection. $990 US, un-used. A good deal as they tend to go for much more. The Nikon SMZ45 was recently discontinued, hopefully meaning that more should be on the market for a lower price. The scope needs illumination though, and I have had to purchase a LED ring light illuminator, which I am still waiting to receive. Very cool device.
