My machine has been with me for 18 years. Ask yourself, is your machine doing what you want it to do and meeting your needs and doing a good job of it?
I bought my LA just before all the computerized machines came out and I sure couldn't afford to upgrade that machine. I would really like to though.
A DHM can be a big investment and like cell phones a new improved model comes on the market every day.
Have your machine meet your needs. My DHM has the original ability to interact with a computer to do embroidery and I have never used it in 18 years, yet I love everything else my machine does, Good stitching, many special stitches and It has never had to be repaired.
Hope you find a machine you love.
peace
