I went the Home Depot paint roller extension (aluminum) route. It is twist lock (you can twist either way to lock it) and extendable to 12 feet (I cut it to 10). Put a fitting I got from my dealer (a Murray's part) on one end and my old mountain bike grips on the other end and voila! a reasonably priced replacement.....the only problem is it bends easily but also bends back just as easily. At least when it bends it doesn't crack like my old fiberglass ones.
