Buy a cheap power tool or invest in a quality one?

A cheap tool breaks when you need it most and ends up costing more in the long run, because you end up buying the same thing two or three times over. If you're going to use it regularly, invest in a quality one from the start - it lasts for years and the work turns out better. Now, if it's something one-off that you'll rarely touch, then a basic one does the job just fine.

It really depends on how often you'll use it. If it's just a one-time thing, like once a year, a cheap one will do. But if you're using the tool regularly, quality saves you headaches (and money down the road).
