smoke pump, slimline or sullivan
 

i have an edge 540 T with a saito 125 and slimline pitts muffler, anyone prefer slimline or sullivan smoke pumps? i would like to use a pump that has a battery selfcontained in the smoke pump. does anyone use the slimline showtime pump? there web site says battery not included on one page and on another page it talks about charging internal battery? i want the most reliable pump i do not want headaches.
