Interesting to note that the M5/9/13 and Mobius are essentially copies of the Goatkeeper and the Slicer was Boss' attempt to ape the Adrenalinn, going so far as to use the phrase "add some adrenalin to your playing" or something very similar.
The Empress and Tap-A-Whirl are cool and have patterns but they don't have anywhere near the control that the Goatkeeper does.
Not a tremolo per se, but the Moog MuRF can also do patterns and sound very tremolo like. For that matter the most expensive solution would be using the MuRF to control the Moog Ring Mod for a true pattern trem.
