[quote]Check out National Electrical Estimator at:
]http://craftsman-book.com/products/info/cbccostbooks.htm[/quote] You can get TNE (The National Estimator)at Amazon for $33 (Craftsman wants $57).
I use TNE, Excel and a copy of the "Home Depot Worksite CD" (which is basically TNE, but I can update pricing everyday).
For a smaller business TNE, et al, are fine...once you get into jobs larger than residential and small commercial, you may want something a bit larger.
