I have been using the Kastar 1900's with good results in MX980, MX990, and MX1200. They have good life, and (unlike some of the other off brands that are a tad large and don't fit well) fit perfectly.
FWIW . . . $30 to URC is just too "rapey" for me . . . esp. when they are just rebranding someone elses battery.
