Foxely starters are very expensive............Denis Simpkin (see above thread) made a starter for me...................it seems so far to work quite well.
The beauty of his starter is that you can use it on your own althought an assistant does also help
It is however not as convieniently portable as a Foxely and having such a large battery in the MGP holding area might not be allowed.
You could of course keep the starter by the fence with the battery outside.............not that I would be planning to do just that
