Of course, you can also get converted pin locks. Ball lock connections, pin lock dimensions. I see these more and more.
I like my 3 gallon kegs, but the price of those things is crazy. You can get two 5 gallons for the same price, even on fleaBay.
For me, the wider dimensions of the pin lock kegs is the deal breaker. I can just barely fit two ball locks in my Sanyo mini fridge. I don't think I could do two pins.
You know what that means? Time to stock up!
I really don't need more, but I keep cruising eBay and Craigslist looking for deal... $50 is looking like a deal these days.
