So what would you guys do? If I tap my own box, the cost will be minimal. Of coure, what if I get shavings in the box? Or it doesn't work for some reason? If I tap the box, I seriously doubt that I would be able to ever return it if something happened to it. So, the caps are $100- the cheapskate that I am, it almost seems worth it. It seems like I would also have more flexibility when it comes to hose routing. What do you think?
