Top and Bottoms have then.. but only personally I have had some bad results using then. Goodyear (across from Cirus) has a better quality (expensive) kit that works well....
For smaller bikes like a YBR I would just go with the cheap ones in Tops and Bottoms. For big bikes and cars where you can regularly go over 100kph I'd probably drop a bit more money. Main reasoning is the tools that come with the kit. The cheap ones might not be made well enough deal with larger tires.
