Most of the forum users who have upgraded to a hid kit have purchased the mcculloch hid kit... it is a tried and true product for us crossfire owners... and as for the hella from autoxclusive... i doubt it is any worse than the mcculloch, especially because it is sold by someone that is known on the forums... Its probably pretty much the same thing for the same price... you should be more concerned about what rating you want...
