I charge the following for equipment:
MFDB+camera: 3950,-
Canon 1ds Mk.II: 800,-
Lens MF: 600,-
Lens 35mm: 300,-
Pro 7b pack with 2 heads: 1090,-
Acute 6b pack with 1 head: 540,-
Acute2 1200 pack with 2 heads: 1090,-
Compactflashes: 360,-
etc. etc. etc.
All prices in NOK. And they come on top of everything else like transportation, photography, assistant, rigging, batching/contactsheets, colorcorrection/base adjusments, compositing.
I differentiate my budgets pretty meticulously (how does one spell that...) giving the client a clear overview of associated costs and estimate time expenditure on every little detail. It's fairly quick once you have an excel sheet established with the nessecary boxes to fill in and formulas taking care of the rest.
It might be overkill, but it differentiates me from other shooters, and makes me attractive to some purchasers, and not to others.
