All of those look way overpriced, research the DIY route. Most likely will end up way cheaper even after factoring in the costs of tools and time.

For a beginner, a single speed unit with a TXV would be the easiest to get working well. Don't cheap out going with a capillary tube - they're not that much cheaper but are less efficient and a lot more sensitive to exact refrigerant charge levels.

For an efficiency boost, the easiest and most cost effective would be to add an evaporative subcooler - an extra coil attached to an evaporative cooler would do. Place that near a window so it would be easy to get the option of cooling with the evaporative cooler directly.
To my surprise, shortly after Naomi Wu gave me a bit of fame for making good use of solar power, Allie Moore got really jealous of her...
