I also got this program as part of the MacHeist bundle. I use it on a fairly old G4 powerbook, and it is not as fast as it could be, but is certainly usable. There was a problem in an earlier version with a crash during search on old hardware- I emailed the developer, and in reply they sent me a beta to try to see if it fixed the problem, which it did. I have no problems with the search with the newest update.

At first, I found that the recipe import (mostly from plain text or html files) was slow and unintuitive, after importing a few recipes I found it much easier.

For me, the big selling points are that SousChef is an attractive way to organize my recipes, attach notes and photos to remind myself about the recipe, and the big screen view for when I am actually cooking.

Simple concept, great execution, great price. Just what I need at work so I can turn the volume down unobtrusively when the boss is trying to talk to me!
