I was looking for a budget flight case and ran across an ad for a Cavin RW12 Road Warrior for $200 bucks. It looks new but then I noticed the ad didn't say anything about being ATA certified. I could get a Road Runner or Gator brand at Guitar Center which I think are ATA certified for just slightly more. Or a ProX ATA. I have no experience regarding the quality of cases. I was wondering if anyone could please shed some thoughts of what might be the better chose of the three brands? Cavin Road Runner Gator Pro X Case Thank you.
