There just isn't one mic for every application, just like there isn't one tool for every job. Would you prefer to own the finest hammer in the world or a 64 piece cheap Chinese tool kit? That depends. If you are a carpenter, and you hammer nails all day long, maybe you want that hammer. If you need a hacksaw, even a cheap one is better than the best hammer in the world.
In the beginning, you need to learn to use the tools, even if you can't afford the best ones. You need an identical pair of small diaphragm condensers, so you can learn stereo recording. Then you need at least one multipattern mic, so you can learn what omnis and figure 8's do. You need one good dynamic, because they aren't quite like condensers. That's the bare minimum.
It's also a matter of style. Would you rather sleep with one supermodel, or 4 cheap ugly whores? No one can answer that question for you, and either experience could leave you unsatisfied.-Richie
