How much more expensive would you say it would be to create a DIY project vs. buying a premade one? Would you consider the expense - both time and money - to be the biggest downfall? Is the best part of it the satisfaction of having built something on your own? Or do you like that you have more customization options or something else?
I think most DIY projects are about the personal satisfaction of doing it yourself rather than cost-efficiency. I know I used to think that DIYs would always be cheaper - for any kind of project - and I quickly found out that is rarely the case.
