Hand registering vs. Buying in the aftermarket

[draggar]

Hand registering - going to your favorite registrar and typing in domain.tld, seeing that it is available and registering it.

Buying aftermarket - buying it from someone else or a company (TDNAM, Sedo, DNForum, person to person, Traffic etc..) or a drop catcher (Pool, Afternic, etc..)

OK, people when should you do which?

What I think:

Hand Registering:

• New technology (recent - MT9)
• Definite development (you will develop it)

Aftermarket:

• (Any hand-registering reason)
• Good domains
  • Revenue
  • Traffic
• Investment (LLL.com, NNN.com etc..)

What else?
