I have a 50 year old New Home, a 4 year old Janome 4900QC, a White and a Riccar....The New Home/Janome's are by far my favorite....saving for a 6600 now. With the Janome the only problem I have ever had was a PEBCASM (problem exists between chair and sewing machine) LOL.
One thing to consider is where you buy your machine. Don't buy it online, please. Go to a reputable dealer and talk to their service department in addition to the sales person. Ask about warranty returns, service charges, whether or not they are willing to help you over the phone, etc. Having access to knowledgeable, helpful and friendly service is one of the most critical components to being happy and successful with your machine. Good luck and happy sewing/quilting!
