I have the Juki TL2010-q which is as straight stitch only machine, I love it. One nice thing it has is a speed control slider, so you can go from very slow up to 1500 stitches per minute. I am a new sewer (just about a year) and I just looked at the seams of my latest piece, and the stitches look pretty darn perfect. So I think if you test drive one of these you might be pleased with the result.
The TL series is the one that can be sold online, the QVP/Haruka are all the same machine but are the models sold in shops (they come with more accessories and at least one has a microlifter, but the machine itself is the same).
