Not the OP, but we had 5 installed last May for $15k US, and they are awesome. Also a big chunk of our cost was due to the fact that two of them required a lot of exterior piping work because they were on the opposite side of the house from the base unit.
Work fantastic in the summer, quiet, work really fast, and pull humidity out as well. In the winter they are great because they allow each room to be its own temp, key for pandemic months where my wife, son, and I all like specific temps.
We had three 6k BTU units, one 12k BTU unit, and one 18k BTU unit and the total cost was ~$18k. We got $1,600 in rebates from the utility for the energy efficiency program.
I am very impressed with how little electricity they use!
