I have a Janome 6600 and have had my 350E for a few weeks and love it.... Easy to use. I don't have a "normal" sewing machine shops like in the westerrn countries so I have had to teach myself and have found it relatively easy to with a little help from this site and other different forums..
Lots of different sites sell or give away for free great designs.

I too have the Janome 6600P and a 350E. They are wonderful machines. My dealer is too far away for casual trips, so I have explored and practiced pretty much on my own. No problems ever!

I have the Viking Diamond and love it. It has everything you could possibly want and more.

I have the brother 400 and love it. Have had no problems and can do downloads from the computer.
