I started building http://www.splatsearch.com A comparison engine with big plans to compare everything in the world. One online marketer and 2 developers building it. Currently the live version is a very different snapshop from the dev version which we roll out soon and just has 14 million sample products. We bootstrapped it and it probably just about profitable even though its barely live.

Wow, i think the most difficult part is the parsing, isn't it? Are you using any open-source solutions or is everything custom-built?

Everything is custom built. The parsing is the easy bit. The architecture is what i find the hardest.
