Heh, I have to watch that video that you're talking about, but from the responses here, it's almost like a Radio Shack setup? I did that on my first recordings about ten years ago....hey, as a teen and jobless and needing to get something down, it worked okay. But it certainly wasn't anywhere near good sounding.
Though, i'm a firm advocate of one just needing the right pair of ears with moderately priced equipment....hell, you guys have probably spent more on one mic than I have on most of my setup. But on the other hand, waiting around to record on the highest end equipment is an arduous and often momentum killing task. "Well, I don't have the ____ mic, so I guess i'm not worthy of putting anything down on recording!!!". I think that if you put enough effort and care into it, things can sound great on a budget....but you have to sit down with enough recordings and listen on the headphones to them and do your research. My problem with the DIY thing nowadays, is that I don't hear alot of time and research being put into the recordings--they're rush jobs on a budget. Of course a rush job on a budget is going to sound like shit.
Good is still the enemy of great. People do things good enough (or bad that they think is good enough), and then they never try to reach the next plateau.
