halti "collars" that go over the muzzle work much better IME than choke chains. http://www.youtube.com/watch?v=EyUrTP3XLp4
ive found body harnesses are pretty useless for training because your putting the points around the strongest part of the dogs body giving the dog more pull where as the halti removes the leverage because is focuses on the weakest part of the dogs body to prevent pulling.
but choke chains are ok if used correctly and from as soon as they walk with a lead. not a big fan of those spiked ones though, if you get a dog who just wont quit then thats gonna really do some damage as opposed to a regular choke chain.
