Cheapest Place for s-10 control arms??

i know a guy who found a set of ART upper and lower control arms for $450, but didnt get a chance to ask him where he got them? does anybody know where i can get them cheaper than $600? or any other type of arms or a place that makes control arms to lay on 20's? I asked Barnyard Customs but hes backed up until the end of July. I need these things fast. Thanks
