Would you replace your own screen on your iPhone or iPod?

Hi, I was just wondering if you would replace your own screen on your iPhone, provided you have the correct tools, videos and guides? And help if you can get access to it?
Thanks

Added (1). I'm not looking to replace my screen, I was just wondering if YOU would do it.

There are online videos showing how to do it. I know someone who did, and it worked out, but then he's an engineer. I just paid the $70 and had it done professionally.
