From the link you've supplied, and the eBay auction details;- the track listings are exactly what I have on my 2CD + DVD set. You'll get the full Roundhouse gig, not the concise version, plus a fascinating documentary on the reformation of the band.

All I can say about eBay in general is be careful. Always look at (and read) the feedback history, how long the seller has been going, and use PAYPAL as a safer payment method. Good luck and I hope you enjoy it when you receive it.
