If you have a German Reformed heritage you might want to try the Reformed Church in the US www.rcus.org.

If you are more congregationally inclined you could try the Conservative Congregational Christian Conference http://ccccusa.ccccsitelaunch.com/. You could also try the Fellowship of Independent REformed Evangelicals http://www.firefellowship.org/.

There are a couple of other Reformed denominations with a Dutch heritage, try the Free Reformed www.frcna.org or the Heritage Netherlands Reformed www.hnrc.org.

On the presbyterian side, as well as the PCA www.pcanet.org you have the Orthodox Presbyterians www.opc.org and the Associated Reformed Presbyterians www.arpsynod.org.

Perhaps your deicision might be influenced by having other churches in one of these denominations near to you. If you post your location on the church locator forum I'll see what's around.

Regards,

James.
