I made my own (similar to the one in the Ali Express link below) for just a few bucks and a little time buy using white plastic cereal bowls, some 1/8 threaded rods, cap nuts and wing nuts. I also built the battery enclosure for it using the a pair of the same bowls.
I made the battery enclosure detachable (via wing nuts) from the rest of the station - so I can take the battery and recharge it - until I have time to make a MPPT type solar charger.
Finally I used a piece of house screen (fiberglass - not metal) for the center portion to add protection from insects. (Wasp have been an issue in my area of the past couple of summers).
I bought the bowls from a local 'dollar general' store for ~ $1 a pair.
[I used 14 in total - but that is overkill - and over sized. :-)]
Threaded rod (4 - but 3 would work just as well) from the local Ace for ~ $4.
[3 will probably be easier to deal with and adjust]
~ 3' piece of rigid PVC tube cut into 1.5" pieces.
You can adjust the size (height) of your enclosure by simply adding (or removing) more bowls.
BTW - I used a Teensy 3.2 controller (which works great with MySensors) on a 'Teensy to Arduino adapter shield', and an Arduino 'Weather Sheild' and instrument package to start with - but I am building a more customized weather sensor board to provide reduced power consumption (much needed!) and more precision.
I'll be happy to send more pics or provide info if anyone is interested.
