Just received my order today--the quality and detail of the blu ray product is excellent! No regrets! I ordered this from Amazon(along with the dick van dyke show in blu ray) when the price came down to around $150 for each product. It's worth the upgrade to me from the definitive collection. Plus, there are new extras. The dick van dyke show and twilight zone blu ray collections are from Image Entertainment--so the quality of both sets is great! This is my first review to write after many years as a buyer and seller on Amazon. Also, received my order from Amazon ahead of schedule. Thanks, Amazon!
