Yes, any Shimano 7-8-9-10 speed road series rear derailleur will work with your shifters.
It's important to select an RD that can handle your gearing setup, so OK to use a regular road RD (10, Ultegra, etc.) if the largest rear cog is no bigger than a 28 and you are using a double crankset.
If larger than that or using a triple crank, might as well go for a Deore RD- any of them through 9 speed will index properly with your shifters. Plus, they are built for off road use and are super sturdy.
Easily obtained through eBay at a very reasonable price, shipped to your door.
