Something else to check before buying is the refills. How do you plan to refill? Some do take the tank and have it refilled but then there is the waiting as well as it often get much more expensive at those places. I like having a standard size tank and go to any welding supply to just drop the tank and pick up another. I find it quicker and the difference between 5,10 or 20 pounds of CO2 is only about a dollar. (5-$11.03/ 20 12.08) You might want to run through some pricing on what it might cost to get a 4 pounder refilled in your situation.
