You dont have to work that hard to get bullseye/combo-maker. Just get a thick rubber band and thread it through a steel bead from the hardware store for about 50 cents at the most. Hold it slingshot fashion just above the practice glass, draw back, let go... and you have a bullseye or combo. Then you still have your center punch for making stars. If you want to get a 'bonafide bullseye maker', you can pay up to $5 plus shipping from a number of suppliers (I think the cheapest I saw was around $2)...it will be a rubber band threaded through a steel bead.
