We install in the Cleveland area. Your standard brand in the Cleveland area would be Hunter if you were to head south to Akron it would be Rain Bird. I have had the most luck with Hunter PS-04 sprays for small turf area's and either the PGP or 5004 for large turf area's. For beds we like the heavier spring in the PROS-12. Have had good luck with the Rain Dial timers but choose the PRO-C for its flexibility and we us remotes for service. And pretty much most city codes are PVB's with some exempt meters requiring RP's. And of course the trusty mini-clik. And 2400T's for valves. Not trying to push anything I am just wondering what is common in the different area's and who has had good luck with what.
