Why HDTV prices dont matter as much as you thought | The Digital Home - CNET Blogs
Some data per the great Don commentary:
Fact 1: you can buy a Westinghouse 42in LCD for the price of a Panasonic 32in LCD

Fact 2: 37in LCD prices are still half the 50in Plasmas sorry Don - contradicting your point…:

Conclusions from looking at the last 3 months starts, amazingly show…

1.  42in Plasmas manufacturers are trying to dump 42in Plasmas at almost half price from two months ago

2. 42in LCDs prices on the other hand are doing very well and drive prices up

3. Mainstream hasn’t reached the 50in LCDs or Plasmas  realm - steady prices so far…

Appreciate your very nice piece on us! Thanks Kristen!

Also, great to know about PriceProtectr (isn’t this tr suffix so off nowadays…) - I guess the two services operate in a web2.0-ish manner doing the best to make the customer aware of more market information.

PriceFad Tracks & Charts Product History
PriceFad Tracks & Charts Product History
July 22, 2007 — 10:58 AM PDT — by Kristen Nicole — Share This

PriceFad is a new site that lets you see the historical price trends of a particular product, to help you see if today’s price is really the best price.

The service pulls data from all over the web to accumulate the price history of particular items. You just type in the name of a product that you’re looking for, and PriceFad will give you the historical price points for that item on a graph. View by month, week or day, and see the data for a range of 1 day to a year. Toggle between average and detailed reports. You can chart the price history of two additional products for comparison purposes, which are provided in drop down boxes that list items available for you to choose from. There is also the option of having email alerts sent to you when a price changes, or you can subscribe to a product via RSS.

This site has a large amount of data for electronic items, such as GPS trackers, monitors, memory cards and television screens. This is probably due to the exacting nature of the product names. It would be additionally helpful to be able to enter the URL or other identifying mark, such as the ISBN number, to help track more products in more ways. A service like PriceFad could be a great ingredient for all sorts of mashups. Similar services include Farecast and PriceProtectr.
