If you have the equipment and know-how, building your own will save a ton of money, and you can make it exactly how you want.. I've heard some of the mass-produced blinds are great on some boats, but leave a lot to be desired on others.. My blind originally had the frame so it would cover every inch of my boat, but I swapped out trolling motors, and it wouldn't fit with the new motor up front, so I shortened it some, and it's been a work in progress ever since.. I think originally I had 200 tops in it.. I was fortunate and had a guy I know help me build it at his machine shop, otherwise I would have been buying one.. I've been constantly improving/changing it and I may be up closer to 3 or 350 into it over the 2 seasons I've hunted out of it.. Still not done in my mind, and it may never be, but it gets the job done
