I used two separate cases for my Esprit, mainly because I don't have a whole lot of room in the boot if I bring a mount as well. I used these two cases from bunnings:
1 and
2, there's just enough room to squeeze an Eprit100 inside. My setup is a little more compact than yours though, I only use an oag so I can have the whole lot assembled and ready to go in about 2 mins.
