OCIA.net has posted their Budget System Buying Guide for September 2007
A quote from the article:
Budget System Buying Guide
For that very reason, we started writing these System Buying Guides a few years back. We have three categories of Buying Guides: Budget, mainstream and Performance. Our Budget Guide has a spending limit of $650, the Mainstream limit is $1,200 and we allocate $2,000 for our Performance Guide.
