I have one of the cheaper hoods...USBody.
I think the hoods ranging around $499 are all made by the same
company. They are passable...with work.
They all seem to come a bit warped, a bit rough, and they all can
quite easily be dicerned from the real deal, or a Thorntons unit.

If you're looking for perfection, find an original or pay for the Thornton unit.
I wound up going with a 4" cowl from glasstek for clearance!
