Actually both. I'm definitely going to build one like Matt F. posted on this site. I've already ordered all the post body parts. This will be an all SS build with all new parts; provided I can afford the valve body. If I can't, I'll have to hold out for something used; but I have no idea what kind of numbers we're talking. I'm looking for the body, cga nut and nipple, and gauges, all in stainless if possible. No matter where I look, I can't get a price quote on line for units like the SGT or the Concoa 432. The only one I've seen is the Harris HP742 at $750. Any help you can give me would be greatly appreciated. Thanks, maknwar.
