I don't really know of any trusted brands, but I bought a plumax enclosure from dealsonic
http://www.dealsonic.com/exen.html and it seems to work well. I've noticed that dealsonic does have a better selection/price then newegg does on the external enclosures.
Other than that info, the only other thing I can offer you is this review of a hd enclosure (not too many of them from what I've read)

Hope that this info helps you out.
