X2 on the tn-100 notcher. Buy a notcher and don't look back, you WILL be building more stuff ! I did my full family cage w/out a notcher and then did my stinger WITH a notcher and the speed and quality was so much better with. My cage was the first thing i had ever built out of tubing and had fun and learned alot. I only wish i had some help to hold stuff in place, instead of using um-teen ratchet straps. Have fun !
