I've never dripped and I'm trying to decide which dripping atty I should go with. Eventually I plan on trying the Cisco HH-357 but they are currently out of stock on the one I need and I'd really like to find a dripper that isn't as expensive. I'm looking for something that is compatible with my Vision Spinner 1300 battery. I'd also like to get some input on if I should go with a low or high ohm rating and if I really need to get a drip shield.
