I have one and love how it cuts so quickly. There is a learning curve, so if you can buy it where there is support, do so!!
I bought one from my quilt shop and they know nothing and even had a very disappointing workshop where the gal had no clue how to teach. The Brother website has many videos on their website, Facebook groups are a good resource and YouTube videos also. In fact, you might view this info to help you decide, but don't let the learning curve discourage you.
