Bob - Thank you for the information on the Conbraco 36H valve. I looked it up and interestingly even though Grainger lists it for $87.50 (3/4") in their catalog page, if you try to buy it, a different page with a price of $97.85 pops up. And this is for the standard version without a strainer. I also would have preferred a regulator with at least one union joint which is not an option on the Conbraco. Nevertheless something to think about. Still would like to get some information on the Honeywell Braukmann regulator. I saw Terry's web page on this valve, but there is no mention there of price or whether he sells it. I even tried sending an e-mail to Honeywell Brauckmann using the url address they provided on their website for contact information. The e-mail came back as undeliverable.
Cass - I understand that the plumbing supply house will charge a DIY person list price which is why I try to avoid them if at all possible. As an example when I was shopping for an expansion tank I ended up paying about 35% less at a discount house then at the plumbing supply house.
