Thanks, since my first post Ive found a 4# Co2 tank for $25, Im trying to get my build to around $250 so this definitely helped.
The place that Im getting the keg from replaces the o-rings before shipping them so thats included in the price
Didnt even know about needing keg lube, will have to add that to the list.
The part im the least knowledgeable about is the tower itself (everything else is self explanatory), so for reference I was planning on buying this tower
So it appears that everything is included in this: tower, shank, faucet etc.
I however do not fully understand the proper way to secure the tower to the top of the fridge, have looked at a couple of DIYs for kegerators but they all seem to skim over this part.
Will hopefully have my build going along in the next two weeks, and hopefully get to enjoy it soon after that.
