I ordered these 2007 PPV's on Friday:
Bound For Glory
I also got the 'Top 50 Moments In TNA History DVD'.
All averaged out at about £5.20 (inc. p & p). 2007 was the year that TNA began to start getting shit (until Hogan and Bischoff came in, anyway) but there was still some decent stuff.
Nice haul. DX '07 is to TNA what The Great American Bash 2000 was to WCW: silly, loaded with gimmick matches, but also very entertaining and capped off with a great main event.
Slammiversary is a mess, but nonetheless very entertaining, mostly for Sabin/Lethal, 3D/Animal & Steiner, Sting/Daniels, Tomko/Abyss, and the best KOTM match ever.
Bound for Glory is probably the best TNA PPV ever, and possibly the best ppv of 2007.
Victory Road is like a solid episode of iMPACT!, nothing more.
Lockdown was horrible. The main event was great, but after the blindfold match, the electrified cage, and a couple of other so-so bouts, it was hard to care.
Hard Justice was weak. Not as horrible as others have said, but still not very good.
