I have 5 FW in my studio right now waiting for my second white one to arrive. It would cost me at least $450.00 to have all of them serviced. So the best thing I got after my FW's is the double DVD those fantastic featherweights. The first time I watched it it made me feel like, "hay I can do this", I am so not good at things like this, but David makes every so simple, and so clear, and repeats like where to oil spots. For me this DVD is a must have, he also has a book which is on my next order list, it has all the info that is on the DVDs, there is also a part on how to care for the 221's big sister the 301. I will take the DVD with me along with computer to the retreat I am going on in Sept, just in case I have a problem with my machine. wouldn't be with out it now, I highly recommend it. Makes me feel safe using my machines, :-)
