To all experienced Plumbers... Madam Goodwrench continues to remodel bathrooms but is totally stumped on which valves to purchase(need 3)... don't want to make any expensive mistakes. Am told the Moentrol is powerful but must be accompanied by appropriate handle,etc. but can't seem to find anyone who knows what goes! Any suggestions? One valve has to be with stops. Don't want to spend megabucks but don't want the cheapo's either... HELP!
