Got mine today. Thanks DDM for only listing $50 on the manifest - Canada customs sometimes doesn't collect their pound of flesh for small dollar shipments (in this case $50 was below their radar).
I note that mine isn't exactly like the one in DDM's original photos in this thread -one of the bolt-on flanges bolts to the main beam from the side (as in the picture), but one bolts from the top (can't see that it would make much difference, but just noticed the difference).
Looking forward to bolting it up and seeing what it does.
