This is exactly what I have been looking for. I think your videos are great and have posted your link on Amazon.com in a book or rather DVD review I had posted on excel 2007 and also recommended your site to view. I have viewed many books on MS Excel, but never felt that they were worth the money. Just recently I bought Excel 2007 Data Analysis and Business Modeling from MS Press and it sucks. I really do hope as you are making your videos for excel 2007 you can incorporate ideas from this book that would be just AWESOME!! I will be buying more of you lessons. One more thing, I would also Like to see more detailed and  complicated examples using the IF statement, VLOOKUP, SUMIF,  and such. Taking a basic example and really building on it.
