Here is an e-mail I got from Bob, 2nd paragraph talks about the misters:
"Yes the PM-50 is available. We hope to get it up on the website by September. Until we get it up on our website, you can order the Pro Mist model PM-60 and then in the special instructions box on the order page, tell us to disregard the order and instead you wish to buy the PM-50. We will send you an e-mail for the actual order and process it accordingly. You can disregard any automated message saying the order was processed. We process all orders manually at our office. The message you will get is a feature in the shopping cart we can't turn off. The total you will be charged for the PM-50 is $129.95 + $14.95 S&H. You can also call us at 845-628-8960 and place your order over the phone if you prefer. We are usually in the office, M-F, 10-4 EST.
You can upgrade the PM-50 to our PM-MNH 90° nozzles which will provide a finer mist, lower water output and can be taken apart and cleaned when they clog, eliminating the need to have to periodically buy new nozzles. The PM-MNH upgrade is $6.95 per nozzle assembly. The standard nozzles that come with the PM-50 can’t be effectively cleaned, so would have to be replaced if they clog. We also have a reduced drip option for our premium nozzles which is $2.95 per nozzle assembly and we also have the standard nozzles available in a reduced drip upgrade which is an additional $1.00 per nozzle assembly. The reduced drip option is built into the nozzle assembly, so will work with any nozzle installed in the assembly. The standard reduced drip nozzles have the valve built directly into the nozzle."
