This is what I want next for equipment! http://www.northernbrewer.com/brewing/kegging/beer-engines/stainless-steel-pin.html
That's pretty cool. I'm fuzzy on the difference between a pin and a firkin though.
That's really cool.
What are some of the pluses and minuses you've noticed using a pin instead of your keg? Is the flavor difference significant?
Contact Paul at UK Brewing. He'll most likely get you a better deal.
I am also lucky enough to own a pin. I got my from geemacher for 160 shipped. Got it to have cask parties ever couple weeks throughout the summer. Super happy with them and if I ever get a firkin I would go back to them for the purchase.
