Mike,
Take a look at the Trailer saver Rigid 26K from Hensley. They are great to deal with and they are just a drive across the MI border to avoid customs and shipping.
It has a Holland Binkley head, very good solid unit. If you don't need air ride, since you have the Trailair pinbox, check it out.
This is what we went with after we wore out the Reese.
