I've had a launch box for over a year and have enjoyed it. Recently, after reading this thread, I purchased an orbiter. For me this has increased the functionality and especially the effectiveness of my launch box way more than I could have imagined it would. The hits and the high are so much more than a launch box on its own, it is amazing.
I've also tried using the launch box with a whip alone and believe this is where the biggest jump in quality over a straight launch box lies. My guess is that any of the options using a whip are well worth the investment. The orbiter is wonderful but I highly recommend anyone with a launch box at least invest in a plain whip or even make your own.
