Well, the 6.x version was free, and 7.5 is $400 for 1 license, even though it's pretty much the same as 6.x. It's a fairly simple SQL query tool - there are plenty a lot more complex tools out there for Windows, for example, which are _free_. There aren't as many for Mac OS X, unfortunately, but that definitely does not justify the price tag.

The 7.5 suffers from most of the same issues as the 6.5: it's fat and slow (as you'd expect from a Java app), and many of the standard Mac OS X keyboard shortcuts do not work (close window for example). Beyond that - it's just a SQL query tool. And it's about 10 times more expensive than it should be.
