Specifically at least under 600$, one that you can put in the yard, includes rain gauge, and doesn't have too many problems.I hope i'm not asking for too much.
If you can spend that much, you can't go wrong with Davis. The usual vendors like scaledinstruments and scientificsales are great to deal with and have very cheap prices currently.
VP2 currently is about $450 and a Vue is down to an amazing $267 if you don't mind the all-in-one sensor suite. The VP2 also has the upside of being able to repair/refresh its sensors piece by piece, which might be of interest.
Add a datalogger (usb or serial) if you want to handle outages if you lose power and missed data would bug you. Add a raspi running weewx as well if you want to generate fancy dashboards, feed places like WU/PWS/CWOP etc., or the like. Even $50 there gets you plenty enough pi horsepower.
A Vue plus datalogger plus pi with a pi display+case would be under $550 if you have a little bit of linux chops and don't mind investing a little time. The Vue+datalogger only is way under $400.
