Dennis Monokroussos reviews Informant's "Paramount" database so we don't have to!

Here's the link.

From his review:

The price is $199; a fair chunk of change, but very reasonable for what you're getting. (Think of how many books you'd need to buy to get your paws on 114,000 [annotated games & fragments].) To my mind it's a very good deal for serious players, fans of chess history and for correspondence players, so if you're in those categories you have my recommendation.

Read the whole thing to see how he arrives at his recommendation.

Monokroussos writes excellent product reviews, so if you're looking for stuff to buy his blog provides an excellent guide for quality material.
