Sounds like you are comparing mechanical (straight stitch only) to computerized (straight, zigzag, decorative) machines.
Of the ones you've listed, I can only comment on the Juki TL2010q. It is awesome! It is quite a workhorse and worth every penny, IF that is the kind of machine you are looking for. But it sounds like you are looking for a variety of stitches.
Juki also makes computerized machines (Juki HZL, nicknamed Hazel). There are several models, starting in the $200+ price range. The more expensive ones have a wider throat and more stitches. Otherwise they are basically the same machine. When it's time to replace my computerized machine, I will check them out since I'm so happy with the Juki I have now.
