I have EQ7 and, for the most part, it is worth the money. It isn't the easiest software to navigate through, though, and I would love it if it had a tool bar where I could pick shapes to design a block with. It has a block library, but the library doesn't seem to have the ability to pick single block components, such as a single triangle, a single rectangle, a single star, a single square and then arrange them in an "original" block. There are a few other ease of use changes that I would like to see in it, but overall it works well.
Just be prepared for it to take a while to learn. Be determined. Use their tutorials. Read the user manual- amazingly, it does have useful information in it. I am a 'brute force' type who would do almost anything not to read the manual, so found that out the hard way.
Above all, try to learn only one or two features at a time. Otherwise, it's like trying to swallow a whale in one gulp - impossible.
