I second going Apache. especially if you want to carry 1000 chips SAFELY in one case. Last thing you want to do is put over 20 pounds of chips in a cheap case. That's a disaster waiting to happen. If you are only using them for storage inside your home, then the cheapos are probably acceptable. But if you're going to actually carry them places, don't risk it.
Harbor Freight has a 20% off of anything coupon right now through 2/6. That knocks the model 4800 down from $65 to $52. The 4800 is the one you need for 1000 chips. 3800 is typically 800 chips or less. I have mine configured for 700 to leave room for setups, DBs and card cappers.
