I'm fairly new to homebrewing and had absolutely no experience with kegging. Once I decided that bottling just took too dang much time, I did quite a bit of online research on kegging. There seemed to be a ton of options, and as the interwebs will generally only help to muddy the waters of you don't come in with a general knowledge, I developed quite a fear for ordering bits and pieces to make my own system. That's pretty strange for me since I'm a pretty advanced DIYer.
I found 4 corney kegs on Craigslist for pretty cheap, so they were actually my first purchase, so had to fit everything to those kegs. I already had a chest freezer I was using for cold storage (7 cuft), so I picked up a replacement (upright this time) and set to looking for designs and plans.
Now that I had a base to build on, I started looking for the best possible price for a 4 keg set up. Believe it or not, this set, fully and we'll assembled, was the cheapest way I could find to get a 4 kegs setup. And talk about simple ordering! I love the drop down choices and pre-assembly, both of which ensure that you get a kit that all works together.
The kit itself is very good quality. I bought the least expensive options for everything (except I got 7' serving lines), and everything was very well assembled, very professional looking, and we'll built. The shanks, taps, and connectors all are high grade (stainless, I think) steel and all use high quality Rubber seals and gaskets. I can see that upgrading the manifold or regulator would have been a positive move. I suppose I'm used to high quality regulators on my oxy acetylene rig, and it's pretty obvious these are not of that quality. They work, that's for sure, but entry level. However, with controlled climate and proper care, they'll probably last forever.
All said, I paid $263 for the kit, $65 for a Johnson Controls temperature regulator on Amazon, $150 for a replacement freezer at a buddy's appliance store, $100 for 4 kegs, and $100 for a filled 5# co2 tank at my local homebrew store. I wish I had bought the co2 tank with the kit ($65 is hard to beat), but I was convinced I could talk a welding supply store out of an out of date one and trade it out at my homebrew store, but I came up dry on that one (and I never strike out with that kind of stuff!).
The customer service guarantee is really what convinced me. I think they say they have fanatical customer service. That's exactly the assurance I needed for this kind of investment. I needed someone that would make it right if needed. So far, all is well, but it's that level of service that sets them apart from other companies.
