ther are ups and downs to both- im not knocking you- to each their own.

the one way bearings tend to get hairline cracks in them and then they dont grab (happens more on roto starts) the recoil sometimes f-up , its a little harder to prime it and start it when using a pull. the cord sometimes breaks....

the box is a beeoch to lug around and if you have a few diff cars it kinda suks. i mark my posts w/ the dremel in the top for each car (etching bit) or they make plates that go in the top for diff cars and your chassis fits perfect every time. its easier to prime and start w/ the box, the batts go dead sometimes, the mugen box is lighter than the crome top.

one thing to remember is that if you ever decide to race its a must to have the box.
