I have EQ 5 and I thought the Quilt Design Wizard is the limited version of it.
I'll have to check.
I too am always trying to get the hang of EQ 5. EQ 6 is the latest version out now, though I haven't upgraded.
There are some very advanced features in EQ 5 that most people may or may not use. Sometimes a more basic package is appropriate.
I design quilts in my EQ 5 program all the time. I download fabric images at their site.
But let's get to the bottom line of what you really want to know:
EQ 5 was around $159 when I bought it a couplel years ago.
Why don't you visit their website? Here's the link:
