Interesting. Thanks for the post. I thought about doing that a while back. But, there are so many blanks that it's hard to make it very useful. Now if you can find a way to fill it all in, that would be very nice. I think a lot of the data is available through TBN and it's members, but would require a great deal of work to compile. I have yet to see a buyers guide that had all the details accurately presented. There was one in "Compact Equipment" magazine a few months back. But, even it had a lot of holes. I expected more from a professional publication. I guess the data is just too hard to gather. Kinda like trying to compare matresses.
