I am saying be cautious of the quality. I have never seen a Spinner Blast which is equivalent to a Bumble Bee for $150. I go to just about every major show in SoCal (except for San Diego this year) and they aren't priced that low. You are correct, my opinion is solely based on what I saw on the website.
Look on Kingsnake. Most Spinner Blasts are well over 250. Spinners 200.
Not here to argue. You know the saying "when its too good to be true......."
