I have used with success the BRL 5' RACE kit.  My only gripe is that
the anchore primer they include contains uracil (part of a UDG-based
PCR cloning system of theirs) which means, I think, that for optimum
efficiency during the transformation step you really should have the
complementary uracil adapter on your gene-specific primer, followed by
UDG treatment and cloning into BRL's specific vector.  I didn't do all
that and it still worked albeit at a rather poor efficiency.
