Has anyone used Electric Quilt before?

I’m just curios as to what people have to say about it. I personally have never used it, but I do know someone who has it and raves about it. She told me that if I was ever going to be interested in selling quilt block patters (which I am), that I would need to get it. I know it would be a great upgrade from the way I currently design quilts. Currently I use paint and a grid pattern, so almost anything would be an upgrade. I suppose as my quilting gets more complex the graph paper just won’t cut it anymore.

So, that is the question I have to pose to the internet nation: What do you think of Electric Quilt?

Also: What generation would give me the most ‘bang for my buck’.

Thanks in advance!
