Microphones. Which one is best for you?

If you are looking for a microphone for your podcast you mainly have 4 different types of options.

1. Dynamic:
Pros.
-Plug this microphone directly in and start recording.
-Small pickup pattern. (Will only pickup sound within 2-5 feet of it.)
- Can travel, be dropped and still work well
Cons.
- Produces a very thin sound unless plugged into a preamp

2. Condenser
Pros
-Best sounding
Cons
- Needs a preamp to function
- Will pickup any ambiance sounds
- Very delicate
- You need a pop Filter

3. USB (A light version of the Condenser)
Pros
- Cheap
- Designed for podcasting
Cons
- Thin Sound with out processing

4. Head Sets
Pros
- Quick setup time
- USB or Analog outputs
- Can read you computer screen easily
Cons
- Many version are too cheap sounding
- Quality versions are pretty expensive

All of these microphones can be bought between $25 - $300. I use the Condenser right now, but am shopping for a headset. Does anyone have any suggestions?
