My jigsaw (a Bosch 1587AVS) won't allow me to change blades, bummer. I could drop it at the repair place, but it is over a hour to drive there and surely over $100 to get it fixed. I was searching the internet and came across a YouTube video that showed how to fix it, and a link to buy the replacement part I'm like to need. It is less than $20, all in. I get to fix it myself too, which I like.
Computers and the internet make us all more efficient and wealthier. Don't know about you, but I think it is so cool.
