the janome you're looking at seems fine.
however, if there is any way you can squeeze a few more hundred into your budget, i would strongly recommend you go with the janome
3160QDC instead.
it comes with a few additional features that really make a difference when making quilts.
the extension table and auto thread cutter are worth their weight in gold.
i am a huge janome fan; own two now.
still ... if there is a brother dealer nearby you might want to check there, too.
you can sometimes find more features for your $$$.
i shopped around when looking for a truly portable machine and found a dealer-grade brother that saved me hundreds (comparing features) next to the comparable janome.
i did not expect to be impressed, but i absolutely love it.
the only downside is that they have really small throats/harps in the mid-to-low-end models.
