Shayne, I am so excited you are going to get some of the workouts. Here are my favorites.
Volume 2 revised (love the music on the challenges in this workout)
Volume 4 (very hard, kick butt workout)
Volume 6 with Candace (extremely challenging, I think the hardest CC workout, Coach Sean's Volume 6 is good too, but not as tough)
Volume 3
These are just some of my favorites, but honestly I like them all. I usually prefer the revised versions of his workouts compared to the original ones. Maybe you could get a shorter one, medium length one, and a longer length one. Let us know what you get.
