out of all the Ingnitor's ive had ......the best one has been the Cheepo venom...My Lhs got a supply of them with meter's that did not work...so they sold them for 5$ a peice.....ive got about a dozen.....1/2 still in the packaging.....they are only 1500mah Nicad's....but they seem to outlast even the Fancy Racer's Edge 4200 Ignitor's....for the price i couldn't complain...and being Lime Green....they are pretty easy to spot on buddy's pit table when yours has mysteriously disappeared from your table.
