Agreed - thats why we are hoping they come out with a hard case for everything soon...certainly someone will. If you had to transport it and needed it protected you could put straps around that foam - there are grooves they would stay in. Not a good solution, but if you had to make it work in a pinch while it in a van or something you could.
You will definitely enjoy it...and let us know if you need any help with it or with anything else going forward.
If you didn't get one, the 18 battery case is a good idea too.
The downside to having 18 or more batteries charged for a day of shooting and then getting bad weather is discharging them all. Hopefully you don't leave you batteries charged for very long and either set up the auto store voltage or get something like a Smart Power Charger. They are a bit pricey - but when you have a lot of batteries to get to storage voltage it does it quick and easily.
