I have the Eversewn Sparrow 25 and it's been great. For classes, I have the Janome Gem and if I had to have only one machine, it would be the Gem.
I haven't sewn on a Brother but I had this experience at a retreat. At the table behind me I heard a sewing machine just quietly purring - sounded like a great machine. I asked my fellow retreater what kind of machine she was using. She said it was a $99 Brother from Walmart! So ya never know...
