I have the Viking/Husqvarna Topaz 20 and have been having a lot of fun with it. My biggest concern is, I can't do Disney with it. Someone once told me that I can buy them from the Brother website and then convert them over but so far have not tried it.
When I got my machine I was at the dealer to have a machine serviced, and he showed me the Viking. Told him I didn't think an embroidery machine was in my future but he made me a deal on the floor model I couldn't refuse. Plus he gave it the full warranty as if it came out of the box. It is a quilting and embroidery machine.
Figure out what it is you want to make and then talk to your dealer. I needed instruction so I highly recommend going thru a dealer.
