That Designio machine looks pretty sweet. I have a Brother embroidery machine very similar to that one; it's the PE770II, purchased from Overstock.com. The only drawback to my machine (in case you run into that model in your research) is that although it has a USB port, you can't transfer designs directly from a stick. I have to run a USB cable from my computer to the machine to transfer the design. Not a big issue but I wish I had a machine that could use a stick because it's so much easier.
Other than that, I highly recommend Brother embroidery machines. This is my second one; I traded up because my first one only had a 4"x4" stitch field, which is too limiting for a lot of designs.
