Houghton is out of business, so new parts, etc are not available from the factory.
IMO Houghton had a better balance and ride than Jerald. I've turned down offers for $2,000 for my Houghton with black metal, and $3,500 for my chromed one.
I know that Double Diamond is building carts that are similar to Houghtons but I've never ridden in one. I think they are starting around $900+
