We describe in this paper a new binary millisecond pulsar, PSR J1738+0333.
Using Arecibo, we have achieved good timing accuracy for this object, about 220
ns for 1-hour integrations over 100 MHz. This allowed us to measure a precise
proper motion, parallax and orbital parameters for this system. We highlight
the system's potential for constraining alternative theories of gravitation.Comment: 3 pages, 2 figures. To appear in the proceedings of "40 Years of
