It's a steal for 1K, getting unlimited weight and +16 slots. The next one is 2K, and you get +16 slots, so I suppose it's even, but you already reaped the benefits of unlimited weight on the 1K, so.....you'd gain more by getting the 1K for multiple chars. Not really a loss if you get the 2K one but...>_>.
Anything higher, simply isn't worth it. You can have 12 characters. Get the 1K upgrade on all characters first, before upgrading them to 2K. If you need more than that, I'm speechless on how you got that much loot.
