How do you carry your extra 4ft Kino Lamps?

[Macville]

So I've acquired two 4ft/4bank kino flo fixtures and now want a decent case to haul them around in. I am looking at the basic two part large black fiber board kino case to stick them in, which is great for holding the fixtures, ballasts, and ballast cable. However, I am striking out on the case to hold my extra lamps (10 total) that might fit in the other case. Kino makes a case that holds 6 lamps, but I'd have to buy two of them and that would be over $100 extra from what I am already spending on just the kino case. So I was wondering if anyone has found a good solution that either lets the extra lamps be stored in the same case or even a separate case that's not absurdly expensive?

Thanks,

Matthew
