The PC channel has some good plugs.  The 1176 is a good emulation, while the CA2a is an outstanding plug.  The PC EQ is another great plug that works on just about any source.  Finally, the best of the PC bunch is the SSL Buss comp, which is really magic on, well, buss groups.  None of them are as good as the hardware, in my opinion, but then none of the other plugins are either. They all work fine.
