If you don't have the matches, I say buy ROH's Best In The World. Joe/Kobashi, Nigel/Morishima, Styles/Sydal vs. Dragon Kid/Horiguchi, KENTA/Aries, Claudio/Generico are all great matches.
Greatest Rivalries is also damn good. Whitmer/Jacobs in a cage, CM Punk/Raven Dog Collar match, CZW vs. ROH, and the 5 star Aries/Strong vs. Briscoes tag match. But PWG Sells out is a damn good set, and a good starter set. It's a hard choice, but I say buy any one of those.

ROH - Best in the World is amazing and at $10, it's a total steal. I haven't watched all of PWG Sells Out, but they really did pack in a lot of stuff into it. I'm not sure which is the best, but it's one of those two.
