Where are you located, Dave?

I am using a purpose-built PC, with 4GB memory and 2 hard drives, an 80 and a 400, with room for 2 more. I use a PreSonus FirePod firewire interface, which has 8 microphone preamps. 2 of the inputs can handle instruments, while all 8 can handle line level inputs. I also have a dbx two-channel compressor/limiter and a TC Electronic reverb/effects unit and a patch bay to connect it all together. The outboard stuff is housed in a rack case for portability and the PC part is in a rack-mountable unit for ruggedness. I have a selection of large- and small-diaphragm condensors as well as some dynamics for microphones.

For software I am using Cubase SX3, which has a steep learning curve, but a lot of power.

I wouldn't mind adding analog capability as well if I can do it inexpensively.
