"i'd look for some kind of return policy and force them to take it back because they werent clear enough in the description.
you get it and play one or two dvd's and if it doesnt work anymore.. obviously you were dealing with somebody that knew the player was going to break very soon.
hold them responsible for not passing along that knowledge to you clearly."
I don't think that analysis makes much sense, given that it's Toshiba being sold by a major chain store.
It occurs to me that single play could also mean it won't play RW rewritable discs -- though I think most modern ones do, earlier models did not.
Anyway, ask the vendor !
