S, this is my biggest hurdle when working with others... I think they do it so they can get the business and then apologize or place blame elsewhere when they are questioned. One of the reasons I've gone through 4 laser cutters in the past 2-3 years... If its going to be 6-7 weeks, I'm fine with that, just let me know up front... Don't tell me 2-3 weeks and then start back peddling. It's the way of most service companies these days. Truly tragic. I absolutely hate to tell a customer a date and have to let them know a supplier is behind. I do all I can to keep communications open with my customers. They usually know the update the same day I do. Just makes for a more pleasant and professional transaction.
Did you take yours to Front Range or Ultimate? I think my 200 customer went to Front Range and he's already got his back and installed. He picked his up 2 weeks after you did....
Hell, I wish I had a coater around here. The closest one (that is decent and affordable) is in Salt Lake/ Midvale, UT area.
