Make sure you consider the whole package, not just the price. We had a Multicam Digital Express. We bought it because of the price. However, the software that runs it is definitely lacking, and the tool setup takes a lot of time. But you get what you pay for. We upgraded to a Zund-- the software that runs it alone is worth the price. Anyone can run it with just a couple of moments of instruction. It really is a night and day difference. So as I say, make sure you check the whole package and see how it works, how you change tools, how you calibrate, everything prior to purchasing.
