I had a 10 needle machine, worked great, loved it but found that I didn't use it that much. It was fun and convenient, it did have a bit of a learning curve. I didn't embroider for profit, most people don't want to pay for embroidered items because they can buy them for less money. I embroidered on my granddaughters clothing as well as mine and some items for friends.
The one you are looking at is discontinued, therefore parts may be difficult to get. I would not purchase it.
