Here is the equipment we've used on the CD.
Protools Digi 002 - $2200
Custom PC for PT - $1500 (we spent a little more but I adjusted the price to today's market)
Reason 2.5 - $250
Drum Sound Library - $40
AT 3035 Mic - $200
Monster Cable Mic Cable - $40
Mic Stand - $50
Total equipment costs - $4280
We only used 1 channel on the 002, and so we could've used an mBox instead of the 002 and probably saved $1600.
Minimum equipment costs - $2680
Now that's money I spent a while ago and have used on other projects, so that cost could be amortized instead of lumped into this one project.
