I use an Igloo Ice Cube. Cost me $20 and works great.
I also batch sparge with an SS braid. I don't really know the pricing on braids...the store where I got mine was having going out of business sale when i got it, so I probably paid much less than the going price. Although I didn't get mine preassembled like they have at bargain fittings. I just got a braided hose and removed the insides.
