I went ahead and got the wort chiller right away, because I'm in a small condo, and there's really not even space in the sink for an ice bath, and the bathtub would just be too much of a pain.
I also went for an 8gal pot so I can do full boil extracts off the bat, since it seems to make more sense to pay 105 for a big pot, rather than 60 for a smaller one and need to move up before too long.
I actually found a local restaurant supply store, and got a 32qt stainless pot, pretty heavy duty for like 105+tax... I previously had a $40 bayou aluminum turkey fryer pot, and the difference in the quality is pretty huge. I didn't think the aluminum held in the heat well enough though, so I returned it and got the new pot. On my old stove though, the burner made the difference pretty small, but we just got a new stove, so I'm looking forward to a rolling boil on my 2nd brew.
