Things to remember when shopping for a machine:
*Machine salespeople have been trained to make the machine look easy to operate, often including sewing on a specially designed firmer fabric.
*Ask to thread the machine yourself.
*Ask to sew on the machine yourself and bring your own fabric swatches to sew on. Include: chiffon, velvet, t-shirt material, silkie polyester or silk, the cut-off bottoms of a pair of jeans with thick seams included! Remember to try sewing thru multiple layers of fabric, and on one layer also. Also, try to do a rolled hem.
*Make sure the book is easy to understand and ask what kind of "return policy" the store has.
*Ask if 'get acquainted with your machine' classes are included.
*Ask for specifics about the warranty, where parts are ordered from, and where the nearest authorized repair shop is.
*European machines have very high standards in electronics and workmanship, (I would choose them over the Asian market) but, for example:
Not all Berninas are made in Switzerland. All mechanical Bernina and Bernette sewing machines are now made in Thailand and Taiwan. No more mechanical machines will be made in Switzerland-means older 730, 830, 900, 910, 930 and 1030 machines will become more valuable. All their sergers by Juki are made in Japan and Shanghai, China.
