Honestly, I'd rather Dropbox keep its 1TB plan and make it cheaper. I pay $9.99 a month for it and use it pretty much only for photo storage; it will be years before I fill it up even halfway.
Just don't delete any local files because they don't remain in Dropbox. Crashplan will keep locally deleted files forever. Backblaze only keeps them for 30 days, and Dropbox removes them immediately (you can access them for 30 days via deleted file history, 1yr if you pony up more cash, but the business plan keeps them indefinitely)
I agree with wanting the 1TB option to be cheaper, but I'm finding fewer uses for Dropbox unless I switch to the business plan, which doesn't make sense. However for a family, you get 5 users for 15/mo and unlimited space. I'm still trying to figure out the downside to the business plan.
