I recommend and have ordered from Paw Paw Everlast Label Company twice now and was very happy with my order and quick shipping. I did not order the stainless steel however. I have ordered both their "E" (11" tall) and "F" (21" tall) style plant markers in the galvanized marker and have gotten the heavy duty zinc plates.
I just checked their website and 30 of the"F" style markers in stainless steel with heavy duty zinc plates is $51.75 with free shipping in the US. Galvanized markers are $36.75, but the next time I order, I will be getting stainless steel.

Edited to add: I also have a hand-held Brother P-touch label maker and buy the 3/4" or 1" white label tape to label these markers from Paw Paw. My original labels from 4-5 years ago are still holding strong and are just as legible on my galvanized markers as the day they were put on.
The galvanized markers have eroded at the dirt line enough that I am now breaking off the bottom of the marker and sticking it back in the dirt. Shorter... but they still work!
