thats cool man,the manual ones are all i have gone for before because of cost but let me tell ya when u get an electronic one you see why not to bother with the mbc's . dont get me wrong the mbc's work ok ,but who wants just "ok" when u have an expensive and prized starlet that youve put alot of work into.u want something thats "bang on". i certainly wont ever use an mbc again.mine failed a couple of days ago,i think there poop.
