I just bought the Lizzie ESP with the Phoenix frame. We compared the frames at the Denver quilt show and hands down, the Phoenix frame is far better. It's user friendly and easy to advance. I really liked that I could easily reach inside the layers to adjust the batting if necessary. It is quite a bit more expensive but I think it will be worth in in the long run. Can't wait to get my hands on it! Should be delivered and set up in the next week or two.
