Pulling the Trigger - Is It Ever Safe to Buy?

In an excellent USAToday article, there is even more proof that now is the time to NOT buy a newbig screen/higher definiiton television. Prices over the last 12 months have dropped from 30-50 percent according to the article, and when things cost in excess of $5,000, that's a boatload of money.

Gloria and I have been socking away for a couple of years since we moved into our new house waiting for the right time, but this article makes me wonder:

When is the right time to pull the trigger on a new television purchase?

Thoughts?
