I would say it's definitely worth taking a road trip to another school to get letters, etc if your Greek school really sucks. You can see the stuff in person and if they make it in-house and screw it up, you can deal with it without sending crap back, etc. Plus you can visit the chapter there at the same time!
Our "licensed vendor" does make nice stuff, but I really don't have an extra arm & leg to use paying for it.
