You also forgot to mention that the Official Priceguide has inclued many chips that aren't listed in the TCR. The TCR also doesn't have the pcitures, which can make a world of difference when trying to figure out one chip from the other on some chips that are almost identical. Then lets mention the facts that are listed, like the issue number and a wealth of other information.

TCR is a great priceguide, and lots of us prefer it it for Nevada chips.

To make a statement that it leaves out almost as much as in includes is way out of line. It's a very valuable resource.

You can always state your preferences without competely trashing the priceguide you aren't fond of.
