Good Morning Rush Fan,
We have a Metcal VPI 1000. We are very happy with the system. The price is competitive, software is easy to use and the picture quality is good. They have a great lighting scheme that illuminates under a BGA extremely well. The endoscopic mirror tip is replacable. The only thing negative that I have to say is the measurement capabilities. All of the measurements are based on the focus setting which is not an exact setting. For this reason, the system must have a high tolerance for measurements. They can get you by in a pinch but I would not rely on them as fact. This system also has a defect library but I suggest caution in the root cause based on either library. For instance, an overheated BGA ball looks alot like a cold solder joint. (without the collapse) It's good for a quick evaluation but I wouldnt use it as a go/no go guage.
I hope this helps Mighty C (A Rush Fan as well!) Hope this helps
