Best Pelican case bar none is the 1510 or now the Air 1535. Of course Pelican's are the most expensive as well but if cost is no issue then both of these are great. Complete with wheels (which is helpful when filled with 1000+ chips) and both qualify size wise for carry-on luggage. Both have plenty of room & can hold up to 1000-1500 chips without issues, are lockable & are tough as nails. I have 2 of them bought for less than $100 a piece on sale and they are fantastic. I would still buy an Apache or other brand most of the time because of the cost but Pelicans are considered the best, but you'll pay for the name/brand.
