2.5 months for me. My CRT started failing in October, so I spent the first month educating myself on the differing technologies, pros and cons for LCD/plasma/DLP. During the next month, I started tracking prices and specs on individual TVs, and started visiting stores to check out picture qualities, along with reading reviews and criticisms of each TV on this forum. In the final two weeks, I figured out which TVs were among the finalists, and then I finally made a decision at the local store, based off what I saw, what the salesman told me, and what they had in stock. Ended up getting a Samsung 4253 plasma, and am happy for the most part. There are a few things I don't like about it, but they're minor quibbles that I can live with.
