Like B&S, I only have experience of my Pfaff 1475cd, which although it does embroider all kinds of patterns and letters, is limited to what is pre-programmed. Although it does have a memory, and I'm able to embroider names etc. The drawback is that the quality on some of the letter styles is iffy, and the sizes are a bit small. I can do monograms, but again, not found them very successful.
I think maybe a bit of research before you buy, and try to arrange to try the machine out.
I came across an attachment which does monograms/letters, but the drawback was that you had to purchase individual cams.
Still and idea though.
Hope you get fixed up.
