Query: Thank you all for the warning!

I have not purchased the Complete Series Collection, but as an owner of Seasons 1-3 I can say that after reading these reviews I will definitely not be buying this set. I would love to own Season 4, but not if it means I have to pay for the first 3 all over again (especially considering 1-3 are such wonderful DVD sets and this set sounds like a rip-off!).I will keep the first 3 seasons and just hope the company will release the 4th on its own.
