If you get them printed on vinyl and only get one of each type they are very expensive. Depending on what you are using them for I have found that painting them works well. Take your backdrop (wood, vinyl, etc.) and hang it up like the picture shows. Draw onto a overhead slide projector exactly what you want to be on your banner and then project it onto the back drop using a overhead projector and then just trace the lines with your paint and you have a much cheaper version that looks really good. Printed at my local sign shop a 10x10 banner is $250.
