Testimonials

  • “We sold Twin Cities Digital all of the equipment from our Tech Center last year when we upgraded. They set up all of the shipping, had it all audited and paid very fast. They made the whole process very simple. If I have more equipment to sell in the future, they will be my first call.”

  • “I’ve been working with Dave at TCD on many projects. Their equipment always looks great, is complete and on time. Great company, I will definitely use them again.”
