I have the Husqvarna Designer Topaz 20 - I have had it for 2 years and love it. Since I have the Janome 6600 MP I didn't want an extremely expensive embroidery machine. It works as a good back up machine for sewing if I need it - but I keep it set up for embroidery. The largest hoop is 200 x 260, I did get the 5D program and it made everything else make sense. I needed the classes - and I would suggest once you figure out what you want, to take a day and go test them out and stay there and learn. Even though my machine came with some software and thread and stablizer you will need more to practice with.
Luckily I have the dealer within 1.5 miles from my home, and was willing to give me a full up-grade if I would trade up within one year of purchase. I like the machine I have, there were a few times I wanted to knock it on the floor and kick it to pieces, but figured I would hurt my foot and still not get it to do what I wanted it to do. Then figured out it was operator error too boot. Also, it wasn't until after I bought the machine and was beginning to branch out that I realized only Brother has Disney - so then I wanted a Brother machine, but certainly didn't want to pay that much for a machine. My machine doesn't scan and I am till learning all the stuff it can and cannot do - but it keeps me busy. A friend of mine comes over, between the two of us we figure out how to get it done - but the classes were a mega help.
So I hope whatever you decide that you enjoy the machine you get.
