I would reccomend an Orban Optimod PC-1100 if you have a spare PC lying around. It's only $1200 with the XLR breakout cable included. We have ours going into an old Optimod 8000A for some hard limiting (and stereo generator) before going into the transmitter.
Even if the computer crashes the Optimod will continue to work, it is only dependent on the computer being powered on.
