Probably a good price, but honestly if you're having trouble with the jig, You may have more trouble with using drill bits. Can be hard to hold and wrap. Can you change the post sizes on the jig you bought? Maybe post a picture of it. You honestly can go with some cheap drill bits if thats what you want to try. After all you're not drilling with them, you're just wrapping flimsy wire around the end of it. You could try a cheap set of precision screw drivers from dollar store too. Many folks have great results using those. Just look for something like a 1.5, 2, 2.5 in the set. Those are good common sizes to start with.
