SWF 902 dual function???

I took a very long look at swf 902 but I eventually purchased a SWF four head machine instead (not dual function four head). A two head seems a bit awkward to me in that I don't see it will increase my productivity to as much as I would like. For me a four head with a single head makes much more sense. A single head will always be useful for doing samples and personalized stuff and such while the four head gets to do the large orders really fast. I made another posting on the Is SWF any good thead that maybe useful to you.
