The price isn't bad at all for new kegs. If I was new to it, I would be tempted, but I have a LOT of cornies, both ball and pin. The amount of time and money I spent getting them all functional..... Something to consider. I'm kind of confused why homebrewers haven't really switched over to sankey. Not so much the old school guys, but more the new folks. Old ways I suppose
I think because most homebrewers brew in 5 or 10 gallon batches and horizontal space is more limited in cooling devices in vertical. But yes, the coupler is superior.
