Just a general question... I'm looking to start kegging instead of bottling. If I wanted to buy an entire keg system how much am I looking at spending? Kegerator and all. Basically, if you could buy a system with everything you'd need and for operation and convenience, what would you get? Is it difficult to set up and maintain? I'd probably want to go with at least a 5 gallon keg, maybe two. Thanks in advance. I'm very new to this part of home brewing and am curious about start up and looking to avoid any pit falls.
