I have had many of those small flight boxes in the past 20 years and never really was happy with any of them.....
This time around I ordered and "real flight box" which should be here next week sometime. Yes, it was costly, but less then the 4 flight boxes I have gone thru in past years combined.
If your interested in looking them over go to....
There has to be some others out there but these caught my eye.

all things considered....very much worth the cost.
