I approached GR-Tek a couple of years ago with a specific need for my business and found that they went out of their way to understand exactly what I required. They did not try to sell me stuff I did not require.
I am still in contact with them now as I'm constantly making sure that I'm keeping up with technology and what is relevant with my business and they always have good advice. I have no interest in taking my business elsewhere and have recommended, and will continue to recommend them to others.
