The prices of used LCD, Flat screens, rear projectors, plasmas, etc is falling like a round brick in a pond. Price compression new technology and added features make it hard to get a decent price for a machine just two or three years old. I've seen people try and price their three year old equipment at about 80'5 of what they paid. You can buy better fo about 50% of what they paid. It's a good time to buy used. Most big picture manuafacturer's are falling at 30% per year. They need better features, technologies, contrast ratio's etc. to maintain the same cash flows.
I'm still on the fence, audio is where it's at for me. Plus cable rates are going through the roo to support these new machines. Where's my Yagi????
