Well I'm close to taking the plunge. My 410 is dying so I figure it is time to look toward a better setup. The decision now is if I should build the box myself, or buy the kit online. I'm no stranger to wood work. My dad and I rebuilt our old house together, I have built stages, and I have a woodshop at my disposal currently. I am curious if building the box on my own will have any real cost savings vs just buying the precut kit that I know will be built right. Thoughts from any fearful owners who built or bought a kit?
