I use their Borg discount as well, and am extremely happy with it. I do wish it were cheaper, but I get 150 GB for $50/yr, which is enough for me with careful rationing.
I wish I had a TB for $50 so I didn't have to be so judicious with my photos, but the ability to use Borg is so fantastic that I can't complain.
You can get get a 500GB storage server for about that price, a bit more for a TB. I run an Ubuntu instance and use borg to backup my home systems to this server.
