My Bernina is computerized Arista 135, not the best of Bernina I know , but I love it. It has worked great for me for about 12 years. Just had it overhauled, for a small fortune. My tune up guy used to work for Bernina when they were all mechanical, he is not very thrilled with the new computerized BIG, intimidating machines. According to him the huge very expensive new models are in for repairs on average about 3 x the first year. They are still under warranty so the eat up the dealers profit. He no doubt has a bias but I trust him, if I ever get a second machine I'll get an old mechanical Bernina, they are real work horses.
