Built this little spreadsheet out in my down time to help me decide how I want to spend my paychecks. The spreadsheet compares cams via Range, Weight, Strength, and Price. Of course there's more that goes into buying a cam than these attributes alone, but it's a start. I left out cams which I wouldn't be interested in buying and the prices I put down were the cheapest prices I could find online that weren't on sale.
If nothing else, the spreadsheet offers a visual overlay of comparable sizes between different manufacturers.
