ez start-never had it or tried it rotostart-crap. the buttom jamed sometimes, it was slow, it was hard to get it in the slot, the battery consantly died. pullstart-small, easy, light, already mounted. my arm doesnt really get tired but when the engien and pullstart are working this would be number 1 or 2. starter box- yes its big, but its soo easy. i havent tried one yet but my frind has one and it starts his new engine everytime within a couple seconds, usually less. if i were driving where i liive, this would be my preference. and a lot of he time i DO drive on my land.
