I have the JHS Unicorn V2, and its wonderful! I'm amazed that Josh was able to make such a luscious sounding, feature-rich univibe in such a compact form factor. They're $200 brand new.
I have my eye on Earthquaker's Depths... it seems fantastic from what I've heard of it, and its very tweakable
If you can get one second hand, the Fulltone Mini Dejavibe V3 is phenomenal. That's the best sounding vibe I've owned, and they retail for $240, so sub $200 is likely doable on the used market. I ended up switch to the Unicorn because its more compact and I needed the pedalboard real estate, but the tone of that thing is killer __PRESENT
