Or if you choose to use a non gfci "Decora" style receptacle, just feed it
off the load of the gfci

The Decora....right. I think that's what I'll do, assuming they come
in 20A versions. The GFCI and the Decora look close enough alike to
give the outlet a symetrical look. A regular duplex beside a GFCI
just wouldn't have looked right, IMHO.
