LBS made way more sense back before the internet. Now, for any given scenario there are at least 100 people who have had the exact same issue you are having and have posted about it online with an ultimate solution. It's not so much winging it any more as doing 20 minutes of research.

But I love fixing stuff and DIY, and recognize that some other people might not. For those people, it's great to have an LBS handy. Which are you, OP?
