The problem with the new machines that have circuit boards, is that the boards can fail and you may not be able to get a replacement for it or get it repaired. I'm lucky in that I have a place close to me that can repair most anything including circuit boards if they are not too damaged. I have a mechanical machine that keeps on chugging. You can shop around and still get new mechanical machines. If you go with an electronic machine, get the one that has all the features you need plus some features that you don't actually need but would be spiffy to have.
