I would NOT recommend the ART SyncGen 192. Too much jitter and starts to muddy things up and pop here and there at 96kHz and higher. (about $99)
No bells, no whistles, but a damn nice little wordclock with three BNC outs. . .the Black Lion Audio MicroClock (about $450)
Lucid GENx192 can usually get one used for around $350-$700 (8 BNC outs)
A couple of bells and whistles, half a rack space, and a very good wordclock. . .Mytek 192CX (just under a grand)
Many others, but start getting into $$$$$.
