Model 3 also has bluetooth, very convenient.
I recently purchased a Graphtec blade holder and blades, and I could not be more pleased with the result. In my opinion it makes much better cuts than the Silhouette blades. When I do an intricate design with lots of tiny details on card stock, using a brand new Silhouette blade, I always have to weed a good 30% of the small cuts. With the Graphtec, the card lifts right off leaving all the bits stuck to the mat, it's magic!
I'm pretty sure there was a much better sale on the model 3 here on Woot, but it was standalone. The problem with the bundle is you may be paying for stuff you don't need.
One final thought: look up the starter kits (glass etching, heat transfer, vinyl, appliqué...) they contain materials and instructions that are fantastic to familiarize you with a new technique. I have made a few really beautiful pieces with glass etching, and all it takes is making a vinyl stencil.
