I recommend using a sit pad because the Bear Vault is basically an oversized child proof capped container and it numbs the hiney. Depending on how you pack it the BV500 can hold up to 9 days on the trail. I have not tried packing for anything longer but nine days of dried at home food was a snug fit. Garcia has made quality cans for years and as mentioned before, carbon fiber ones more recently. Our troop got a discount price on them years ago, but expect to pay $70 - $90 for one. Other companies are similar but not exact and all offer smaller versions for the weekend treks.
+1 on BearVault. I have a Bearikade (carbon fiber) and it's a good bit lighter, but also 2-3x more expensive. The BearVault is a great balance between weight and price, unless you plan on using it all the time. if so, get a Bearikade.
