I have the same Bernina I bought 10 years ago and will never ever get rid of that, in fact, I just bought another at a flea market. Needles, pins, mats, rotary cutters and rulers are the same ones I started with 10 years ago. I buy blades in bulk off ebay and when they skip, they go. I bought some used office chairs on wheels cheaply and have no clue when I will replace them. I use irons until they stop, which they haven't for almost 10 years. Seam rippers do need to be replaced as I have had some of mine for 10 years and they are difficult to use, sure wish I sewed so good I didn't need them !
