- 7/2001 estimate:                                         11,848
- 1/2003 estimate:                                         12,525
- 1/2004 estimate:                                         13,478
- The present estimate:                                 26,062
- The major difference comes from:
-    - Added Canadian labor cost/Pre-inst.    5,000
-    - External PV has been costed:                 3,024
-    - Included scintillator readout:                    500
-    - PMT’s have been included:                      500
-    - Full readout (85%  100%):               1,500
-    - Added rails/shipping cost:                    2,000
