Typically,
a brand new Irritrol RD-900 R system installed by a landscaper would be around $325. Save yourself $200 with just a timer module replacement.
Note: This is only the controller that I am selling and not the entire gray weather proof case (aka protective housing). What you see in the photo is exactly what is being auctioned.
Also, I do purchase used and broken RD-600s, RD-900s and RD-1200s timers for $20-$30 each working or not working if you have one laying around. It is one last thing to be tossed in a landfill plus you receive cash for your old timer / controller.
If you have any questions, please contact me via email. Thank you and good luck on eBay.
