electrosports makes one, they supplied moose with there HO stators before moose discontinued it. my second light stayed on on for a few but it slowly died just not enough voltage in the battery to keep it going. also i hear a lot pf people say bad things about ricky stator but 2 of my friends run them and havent had any problems in the 4 years they have ran it. but i would suggest Electrosport stators as well. and plus ricky stator is just over the hill from me about 25 miles or so.
