That Sunmachine appeared at my local GC a few weeks ago, but despite probably being priced right for it's vintage, it's way outta my range for that sort of thing. But then again, I hesitated on a $70 BAT Fnord v3 for a day too long (same location, somehow), & am still a bit miffed, but probably not as sad as whatever lonely soul sold it to them for $35 in the first place

.
Also, there are two 3-knob DBA Soundwave Breakdowns on Reverb for about $125 OBO w/ free shipping each, if anyone wants to take the plunge
here ($120) &
here ($125).
And if you like your flangers yellow & swell:
Ibanez Swell Flanger -
