Excellent company. IMO they make higher quality plugins than Waves or FF, although Waves has been quite impressive with their recent releases.
Vertigo VSC-2 is one of the best compressor plugins on the market. elysia/brainworx stuffs are great too, and I'm really digging the free bx_opto Pedal which is far more than usable. Their plugins are a bit pricey indeed but definitely worth it (and they do sales on occasion)
