i too have high praise for EQ.
i only downside would be, if you only plan to use it to make 1 quilt it would be a waste of money.
its rather costly and if you put out the bucks for it you really need to use it.
i've used it for every quilt i've made in the last 7 years - either for the block design, border design, or the entire quilt... but every quilt has some form on EQ in it.
