What are your favourite box sets? In no particular order, mine are: - 3rd one's fantasic! - a oldy, but a classic! - amazing footage on this - finally got it! - absolutely hilarious!

I'm a big fan of Friends and have been for years. It's my birthday coming up and I've asked for a - but it's a lot of money to spend. The DVDs were a lot cheaper at Christmas so I missed out there, but it's too long to wait for next Christmas! Does anyone else have it? Are the extras they include worth buying the box set for?
