Hi I'm currently happy quilting on my Viking but definitely want to add a USED Bernina to my stable in the future. I wouldn't buy brand new but would like a used but computerized model. I don't go to classes and BSR is not a must-have (unless you convince me otherwise!!). I really just want the even straight stitches that Berninas are known for. I come across Berninas posted for sale on Craigslist and wonder if there is a model I should wait for and purchase when the opportunity arises either from a dealer or on craigslist. The question is, which model? Virtuosa? Artista? Aurora? Just as a realistic, current example- my local craigslist has three separate listings- a 440QE ($1400), a Virtuosa 153($600) and a 1230 in cabinet($700)? The range of prices and the pros and cons of newer vs older make it quite difficult to decide and its difficult to test them out side by side so I would love your testimonials! Do you have a former Bernina model you still use and love and would recommend?
