As you may have noticed, there are now about a bajillion mic's in the $100 - $300 range. I don't run a studio, but I'm a home recorder who's gone through the process of buying things, and then trying to "upgrade" mic and pre's etc. I don't see a huge difference in the budget mics, but they each have different personalities (as do the budget pre-amps). The trick is to find stuff that (1) works well together, and (2) suits what you need.
Most of us recording at home don't need well-rounded mic collections - just stuff that works for what we do. And the best equipment for you will almost definitely be different than the best gear for me, or the next person.....
