If you want an FM Synth that gives all that you are used to, (As well as more advanced features) and don’t mind using a computer (Or have a keyboard that will accept VST) then there is the FM8 from Native Instruments, http://www.native-instruments.com/#/en/products/producer/fm8/

NOTE: You can also download a trial version
