Mini Split Heat Pumps

Hi there,
Does anyone have experience with some of the new low cost Mini Split Heat Pump now available for under $1,000 for a 9,000 Btu unit?
Building a low energy house and only need a small unit but prices are all over the place from $6-700 up to $2.000.
Hard to find good reviews on these units. Any in put is appreciated.

I have inspected several homes that have had Mitsubishi mini systems for some of the rooms. One home had 7 of the units. I don’t know about other manufacturers as I only have experience with the Mitsubishi brand. They functioned as intended.
I do not know about usage costs.

I find a lot of Mitsubishi Units cooling server rooms, must be popular for a reason.
