JCrow- It's $29. It was your money. You're an adult. You have confessed to some degree here on this board.
Don't let guilt take from the joy of your great purchase. Do what will make you feel right about it. Pray about it and the answer will come to you. You will do what is right for you and yours
Enjoy your cutter and congratulations on your purchase. Let go, jump in with both feet. Life is short.
All that being said- No one, not nobody tells me how to spend my money.
Have a great day. Do good stuff and don't sweat the rest.
