I have the Janome 6600P and love it. When I bought it I told the sales rep all I do is sew, I don't embroider, I don't make fancy clothes and she showed me the 6600p, because it was the on I went in to see, and did not try to sell me anything else. Two years later I went into another place, closer to my home and they had all sorts of embroidery machines and suddenly I was hooked. It's the Husqvarna Topaz 20 - doesn't have a lot of bells and whistles but does a nice job of embroidering and will do everything my Janome does - so I do use them both all the time. Try and stick to your guns, buy only what you can afford and don't look back. Someone will always get a better deal, there is always something else they will try and sell you.
And enjoy what you get. That is what is important.
