I have only managed to find pictures of several different types. It seems that the average price for a new one is about $2000.00 here in Red Deer, Alberta, Canada. Almost all of them are in the 6000 pound vehicle weight range or higher. There does not appear to be any offered in the 3500 pound range. I specialize in Honda Civics and Accords and they only weigh 3200 max. I may eventually try my hand at designing and fabricating my own.
