Purchasing a TV online?

I have a 55" Samsung and a 40" Samsung 3D LEDTV; both purchased through Amazon.com this year. I did my research prior but found their prices and quality the best at the time. The 55" was new and the 40" was refurbished. If I had to do it again, I would buy both refurbished since it came 'like new' and I basically paid around $800.00 for the new box.
