I just started upgrading to rank 2. I'm level 28, and the cost to upgrade was the full 55,000 gold listed. Price does not seem to be reduced based off level.

Also, it ties up your ability to upgrade anything else during the full time it is upgrading (like any other building upgrade).

Good luck if you plan on going to the end without spending nanos. I'm not going to try for it, personally.
