No. When you compare similar size to similar size the difference is not a pound and the price difference is more than $100. So depending on the size you might be either:
1. Spending $169 to save 10 ounces.
2. Spending $152 extra to save 5 ounces
From a post I made on another forum:
"The numbers are:
* Bearicade Weekender - 650 cubic inches, 31 ounces, $249
* Bearvault BV500 - 700 cubic inches, 41 ounces, $79.95
or for the smaller size:
* Bearicade Scout- 500 cubic inches, 28 ounces, $219
* Bearvault BV450 - 440 cubic inches, 33 ounces, $66.95
Personally I find the weight savings of the Bearicade models to not really justify the price, for me at least. For the large size $169 extra to save 10 ounces might almost start to look tempting, but $152 extra to save 5 ounces seems very dubious to me. Those would be some of the most expensive ounces saved on my list if I went that route. If I use the Bear Vault models I can buy both for way less than one Bearicade of any size and use the one best suited to the hike I am doing. The flexibility of having both is nice because when you can use the smaller one you can probably same additional weight by taking a smaller lighter pack. In my case on trips where the BV 450 is enough I am likely to be using a 10 ounce lighter pack as well for a weight savings of 22 ounces over the BV500. It is even 12 ounce lighter than if I had the Bearicade Weekender. Obviously I'd save weight with the Scout, but how many folks are willing to splurge for a Scout and a Weekender. Having all three Bearicades would be ideal but $762 would probably be hard to justify for most of us.
I figure that I can fairly easily get to a base weight of 11-12 pounds (depending on how much clothing I take) with the BV450 even if carrying a few luxury items. At that point I am really not willing to spring for another $152 to save 5 ounces.
On the other hand if you need a really big canister the Bearicade Expedition is in a class by itself as far as I know. I sure as heck would not want to use it on shorter trips or ones with frequent resupply options though. I guess if you are doing one big trip where you need that capacity renting or buying and reselling one makes sense. I really don't see it for the smaller sizes though unless you will only need a canister once."
