Sounds like all you need is a HLT and possibly another stockpot. I use a cooler with a homemade braid and batch sparge. I heat my strike and sparge water on my stovetop then use my turkey fryer outside. Works great and I get pretty good efficiency.
Just buy a six pack here and therfe of pry-offs and you'll have a ton before you know it. That or check your local recycling center.
By doing just those two things I have more bottles than I know what to do with.
Just ordered a pound each of cascade, northern brewer, and willamette. I thought this looked like a decent mix for some american and english and possibly german ales?
Great prices though I'm waiting on a shipping price....
COOLING: 25 ft. may be a bit on the small side. I use a 50 ft. and it cools a full boil very fast. As for not getting it below 70 degrees, what is your ground water temperature? If it's not much below 70 you won't be able to cool past that with your i/c.
