i've been kegging for several years with an old regulator a buddy gave me. i'm looking to get a new regulator and i'm not sure what make/model to buy. i typically only have 1 keg on tap at a time but would like to be able to serve 2. i haven't decided yet if i want a dual regulator setup or if i'll go the path of a manifold etc. any thoughts or links to products you'd recommend are greatly appreciated. thanks!
