I would still recommend the wmr968 as a good starter station. Served me well for several years, and still have parts of it in service going into year 6.
Ambient still has it in stock. $229.
The anny is wireless, so you dont have to sacrifice wind for rain/temp, or temp/rain for wind like with the all-in-ones. You dont need a $120 cable to hook up to the pc. And you can make a rain gauge heater for a few dollars (add $20 if you dont have an existing low volt lighting system you can steal power from). An extra sensors are around $20-30. You can monitor an extra room two or three, and/or the poo/spa/hvac. And in a few years when your outside sensor fails, you can use one to measure your outdoor temps/humidity. If you buy, I would grab at least one thgr122, or THGR968 while they are still available as a backup.
