Money isn't the issue, I want the best value and that doesn't mean the cheapest just not wanting to spend money on things that aren't needed.
I'm thinking one that has 25l containers that are easy to change rather than a container that needs refilled while I'm out.
good call on that, its very easy to just swap then over, less time wasted
all them style trolley's are just glorified sack trucks
buy your self a nice sack truck and a pump box ( from cleantech ) and your all set to go with a battery
get a nice sack truck and it will last, afterall its designed to move about loads all day long
