The Doubletalk emulates the Echo II and has its own synth in addition that uses an additional slot. I did business with RC Systems years ago and Randy, the guy who runs it, shafted me. There's information about it in my not recommended businesses section of my web site. The synth is ok but you definitely need to figure that what you buy is exactly what you get and hardware support especially may be lacking regardless of what you're told. Exactly how much the synth costs depends upon how much onboard memory you have added to it.
