Researching before buying

When it comes to buying technical or mechanical stuff, I make sure I read up on as much information first and only then attempt going out to buy something like this Delta machinery, so I know exactly what I am looking for and don't end up making a fool of myself. Having the internet to search for stuff makes it a lot easier than having to go to the library or dig out a reference book, so buying complicated stuff has become so much easier now. I will admit that it has made us a bit lazier about doing the work and putting in the effort to search though.
