It all depends on how often you want to fill it. I have quick disconnects on mine and fill it every 4-5 months (It is 5 lb.)
Very simple operation. If it is going to be a pain for you to keep filling it, I would go with a 10 lb.

it is cheaper to fill a 10 pounder as opposed to a 5 pounder twice, plus the hassle factor as MarksReef points out...if you have a nearby beer brewing or gas supply house, that will help...if it is 30 minutes away, that's another story.

Initial purchase price isn't a lot more. The only real disadvantage to the 10 pounder is that it takes up more room which may be in short supply.
