tgm is definitely right about condensors. Just a note of caution though, they pick up
everything, fan noise, traffic, birds. You do need a quiet room.
Another suggestion (that may get shot down
). Behringer make some low-cost mixers with phantom power that work well with condensors. They also make reasonable mics, as do Samson.
Don't be tempted by the Samson USB mic. Pretty good quality, but the drivers (allegedly) suck. Minimum 23ms latency
