Hi Josh, welcome to the community.
Overall you can find many different opinions / discussions on pros / cons of different PWS(s), but my personal recommendation tends to be AcuRite 5-in-1 system. Be sure to get a version with a network Hub, like this one (link). Setup is pretty straight forward and it usually comes with everything you need in under $150.
The next more affordable option tends to be Ambient Weather systems, with main advantage being a solar battery on some models, but they also come with a potential issue if your neighbor gets one too, more on this here (link).
The cheapest “professional” stations tend to be from Davis, but they are not without their own problems (link), and frankly with 5-in-1 sensor being that much more affordable, I prefer to not be as attached to mine and be in a position to afford a replacement at the first signs on trouble.
Overall, you are more likely to find a PWS with support for Weather Underground, rather then CWOP or pwsWeather.com which are the networks supported by Rachio. Fear not, www.wufyi.com is were you can relay Weather Underground data to pwsweather network, free of charge and without requiring a local computer.
