appreciate the feedback, I went ahead and placed my order. I probably will eventually expand, but I have a store like 8 miles away I can visit. I'll probably play around with the 4 foot tubing first then change it once I'm comfortable with removing each little piece. It probably isn't as complicated as I'm thinking it is, but it'll be easier for me once I have it in hand. Glad to hear the 2.5 gallons are high quality! I hope the regulator is good too, it's the main reason I didn't buy the 3 gallon system from northern brewers.
