Cost effective and state of the art may be mutually exclusive.

A state of the art system may use a program like Expedition. It has current data built-in. You input your boat's polars and download grib files. Expedition will provide you with a chart of the course to steer as well as a table with the course to steer and target boat speeds in regular intervals. The grib files come from SailDocs via email.

One user has developed a couple of add-ons that provide tables which indicate whether or not your are sailing to the target speeds.

I think Expedition runs about $1300.
