I got my E360s for 160 ea., I think. The deciding factor to get that case was the ability to hold 2 full face helmets in each one. I think they're the only ones that do without spending a good bit more. May want to double-check if you wear an XL or something.
I also got the quick-release mounts, so my bike doesn't have the racks in it when I'm not carrying the cases. Check out my garage.
And check out the "Show us your FZ6 in Touring Mode" thread for more looks at what ppl have.
