Hey all

Our team considering omni wheels for this year. We saw that andymark sales them for $100 (
http://www.andymark.com/product-p/am-0432.htm ) while vex sales them for only $25 (
http://www.vexrobotics.com/vexpro/mo...ni-wheels.html ).
Does anyone know why the prices are so different? Do vex-wheels break or have any other problem?
Thanks ahead!
