Current Plan Offerings from MuseScore/Muse Group

Gang:

I can't, for the life of me, find a current listing of plans available with price points outside of my upgrade options for the various levels of Musescore access. You can't view tiers without creating a login. These have to be listed somewhere, no?

My department is considering springing for subscriptions for everyone, but I need to know what that might cost, depending on our needs. We don't need the instructional bits, but access to pro scores is important. I'd also like to get an Ultimate Guitar subscription so I can accompany my pop students (and transpose from my phone or tablet).

I'm also seeing no difference between the 70$ and 85$ tiers? Is that correct?
