NGK iridium spark plug question?

[EvilMike79]

I want to buy an iridium spark plug and I found an NGK plug for $10.50, is this a good spark plug or can I find something better under $20?

I bought the NKG iridium spark plugs. They work great so far.

I've been thinking of upgrading my plugs to the iridiums but am curious what the actual benefit would be?
