So something to keep in mind is;
1. There are several tools on the market at various price points
2. Price is always an issue but should NEVER be the issue is buying anything, instead look at the value provided, i.e. accuracy, completeness, support etc..
3. The more expensive utilities cost more for a reason, i.e. the old adage of you get what you pay for couldn't be more true. Some fail miserably, others appear to work yet when you look close at the resulting data its clear they are neither accurate
nor complete. There are really only 3 great utilities on the market, Lucid8 makes one of them DigiScope, however since I am obviously biased if you want to discount us then the other two tools to consider would be PowerControls or Dell/Quest Recovery
Manager for Exchange.
