Gofli,a Sullivan Dynatron here in Canada sells for around $100 + taxes [X(]so $40 sounds quite a bit cheaper doesn't it.Starter cone didn't cost me a thing as I already had one as do most flyers on their standard starters.Invest a little effort here modifying a bolt and it doesn't get much cheaper than that dude for a brand spanking new 18 volt device that will start your Homies...........and don't forget I'm talking Canadian dollars here so that works out to about $34.53 US.The beauty here is that it can be used as so much more than a starter at the field(the field repair manager will love ya) and you aren't reliant upon your field box as a power source every time you go to start your engine with your starter.Complete portability.
