This is a topic that depends on a lot of thought and knowing who has what already. What to buy??? If Bobby has a K2 and we don't have any Camera's should I buy a Camera? Well that depends on if you are stay with that group or going to join some other group and what they have or don't have.
EXAMPLE: It is best to start with a Digital Camera, Digital Video Camera and a K2 meter. Why? Why not buy a Digital Voice Recorder? Good question, here is a logical answer, if you have a Digital Video Recorder or even a cell phone you can use that for EVP's but without a K2 or other like equipment you are not able to do a full investigation.
I hope that kind of gives you an ideal about this Forums (threads) use.
