The truth is, unless you've had a lot of experience with signs you probably can't tell how well they are made, much less what kind of potential trouble they can give you in the future. We've seen every type of problem with poorly made signs that you can imagine, and many that you could never anticipate - from vehicle graphics that fade out or curl up in a short time to lighted signs that fall apart when you try to replace the lamps.
There are a number of ways to cut cost on signs, and the "savings" are not necessarily passed on to the customer. The fact is, when you purchase a sign you are depending on the manufacturer to know what they are doing and to not take advantage of you.
If the price sounds too good to be true, it probably is. We promise to do it right the first time and stand behind our products.
