i use the team magic one myself.
its really handy, 4 small seperate draws to put parts in, 1 large draw with a 10th TC fits nicely in
a tool holder on top, wheels....a handle that can be pulled out.
also has the option to fix the team magic transmitter, and team magic starter box bag to it..and a slot to hold setup board aswell.
VERY handy if you ask me..but that sportsworks one looks fairly good to.
but team magic is cheaper (i think)
