Hi Jackie,
That Block Rockit is a pretty sweet little machine! And more affordable than most. It's only available through Lynn and Kathy of KathyQuilts. They're really good with customer care, and make lots of videos to help you -- loading the quilt onto the frame to cross-hatching a quilt. Here's their website...
