Am I allowed to ask why e W o n is censored? Odd.
I've used the Pheonix Contact 2314008, and the Red Lion SN6901AT. Both work fine, Red Lion seems to have more features and is cheaper. Both probably too expensive for you though.
2nd that "features determine price." Look at DIN rail mount wifi anything, minimum $500 when in reality it should be probably $80-$100.
