Massive tool. Using it for 3 years now. We could not live without it. For a free tool, we got great support as well. Questions are being answered by the author, even if it takes a while. Incredible. If you work with a lot of new articles every season, especially with configurables and singles plus customer group prices, this is what I recommend: GO FOR MAGMI! It might take you a tday or two to get it started and to sort out the hickups (needs UTF8 format >> use MSOffice Calc to make the csv file) - but then, what a relief.
