Home Brewers - Have you used the mini-kegs before?

[BeerAdvocate]

Are you talking about the Heineken mini kegs?
They do make smaller 3gal homebrew kegs, but for the price you might as well just use the 5 gallon soda kegs.
I built myself a little kegerator that holds 2 five gallon soda kegs.
I used craiglist for the fridge and I have less than $200 in the whole setup!
