Need some help--ID phono needle and where to purchase replacement

Have a cartridge I like (OK, it's a low-end cartridge, but perfect for the turntable) and would like to replace the needle.  Could anyone identify the cartridge/needle, and where I could find a replacement?   Many thanks for all help!  Jim
