Well for me, one of the BIG things the wizards do, is allow me to trigger off zones. This may not be a need you have right now. But it lets me fire a set of remotes/strobes in one place, or another set in another place. Either independently, or at the same time. They also have a high-speed sync mode which lets you trigger speed lights and some other lights at speeds higher than 1/250. For fill flash, or for things that are moving VERY quickly, this can be a terrific advantage.
They also relay for each other. So if you get out of distance, you can set another unit in the middle and move further away, and the unit in the middle will act as a relay to the further most point. You can set up MANY this way. You may never have a need for that, but I was reading a story during the winter Olympics where a photographer needed to trigger remotes for the bobsled event. And by relaying, was able to put remotes the entire length of the track. Over 2 miles if I remember correctly.
It sounds like you got a good system at a VERY fair price. I am not knocking it at all, was just curious if you'd considered the Wizards and decided against them for some reason. I see price was an issue in your decision making, so that is WELL understood.
