Thank you all for your sharing your toughts. I feel better knowing I'm not the only one who likes bell and whistles. On the other hand, I sold a brand new Viking Tribute a few years ago (excellent machine, never gave me any trouble) because after finding a vintage Bernina 831, I was just not enjoying the Viking anymore. Mighty, I think you are right: every sewing machine have his place.
It would be so nice to have a dealer who would have "in stock" all brands of sewing machine (vintage AND modern) to be able to try it all and decide after. One have to go by trial/error.
