I "think" we have the impact one, had it for years. To be honest I haven’t needed to change it. I don’t know about you, but when we get asked for a sign it’s normally out sized to the clipart/sign supplied on disk. (scaling up, down not possible… so we have to create our own blank and use make the graphics and text fit. signs we don’t have are normally just the same graphics, colours etc but the wording is changed or shape of sign.
Disks that offer more signs undoubtedly help better… but you will find you will have one sign, laid out 10 or more different ways. Which is very easy to do yourself…
Also watch out for signs that offer U.K. and U.S. road signs and safety signs. Basically these make up numbers but half the disk is unusable.
